Academic and research phrasal verbs

US academic prose is sometimes caricatured as Latinate, passive, and PV-light. The caricature is wrong. Open any current article in the Journal of the American Medical Association, Harvard Business Review, or The Atlantic’s long-form science section, and you will find dense use of a specific class of phrasal verbs that signal academic stance — referring to prior work, building on findings, drawing on sources, laying out arguments, bearing out hypotheses, honing in on causes. These are not casual PVs; they have a formal register because the particles often calque onto Latin prefixes (build on ≈ adstruere, draw on ≈ attrahere) and the verbs themselves are short Germanic anchors that ground otherwise abstract academic prose.

For Russian-speaking C1 learners, the typical trap is the opposite of the casual-PV trap. Where casual PVs get over-replaced by Latinate verbs, academic PVs get over-replaced by even more abstract Latinate verbs — utilize instead of draw on, elucidate instead of shed light on, demonstrate instead of bear out, focus on instead of hone in on. The result is prose that reads as machine-translated academic Russian: nominalized, abstract, particle-stripped. The C1 native style is to mix Latinate concept verbs (analyze, demonstrate, postulate, validate) with short Germanic PVs (build on, draw on, bear out, lay out) for rhythm and clarity.

This lesson covers about 16 academic and research PVs grouped by what they do — present arguments, build on prior work, draw on sources, confirm or relate findings, focus and expand, and reference correctly.

Presenting and laying out arguments — set forth, lay out, write up, expound on

The verbs of structuring and articulating an academic argument.

• set forth (separable, but typically used with the object after the particle) — present, state, or articulate (a position, argument, or set of facts) formally and systematically.
  • The author sets forth three main arguments in the introduction.
  • The hypothesis is set forth in chapter two.
  • Set forth your case in writing.
  • Register: formal-academic. Slightly elevated; common in legal briefs, philosophy, and policy writing. Less common in spoken English.
• lay out (separable) — present systematically; explain in an organized way.
  • The paper lays out a framework for analyzing the data.
  • Let me lay out the argument step by step.
  • She laid it out clearly in the abstract.
  • Register: academic-business-neutral. Less formal than set forth; more common across registers. Use lay out when set forth would be too elevated.
• write up (separable) — record formally in writing (results, findings, an incident); produce a written version of work already done.
  • I need to write up the results before the deadline.
  • He’s writing up his dissertation this summer.
  • Can you write it up by Friday?
  • Register: academic-business. Implies turning notes, data, or experience into a formal document.
• expound on (inseparable) — explain or develop (an idea) at length, often elaborately.
  • The author expounds on the implications of the findings.
  • She expounded on her theory for forty minutes.
  • Let me expound on that point.
  • Register: formal-academic. Slightly elevated; can sound pretentious in casual contexts. Common in literary criticism, philosophy, and lengthy commentary.

Building on prior work — build on, build out, draw on, draw from

The verbs of standing on others’ shoulders and extending or extracting from sources.

• build on (inseparable) — extend or develop (prior work, findings, ideas) further.
  • This study builds on previous research by Smith and Chen (2019).
  • We’re building on the framework she established.
  • Let me build on what you just said.
  • The dissertation builds on three decades of feminist literary theory.
  • Register: academic-business-neutral. Standard verb for citing one’s intellectual lineage. Russian основываться на maps cleanly. Common in introduction sections to position the current work within a research tradition.
• build out (separable) — develop fully; flesh out (a structure, plan, or argument).
  • The team built out the prototype over six months.
  • Let me build out the second half of the chapter.
  • We need to build out the methodology section.
  • Register: academic-business. From construction (building out a frame to completion). Different from build on (extending prior work) — build out is about completing your own structure.
• draw on (inseparable) — use (a source, resource, body of evidence, experience) as material for argument or work.
  • The author draws on twenty years of fieldwork.
  • We drew on multiple data sources for this study.
  • She draws on classical philosophy in her writing.
  • The chapter draws on archival material previously unavailable to scholars.
  • Register: academic-formal. Common in introductions to describe sources. Compare with draw from (more extractive, specific source) — often interchangeable in practice but draw on feels slightly more general.
• draw from (inseparable) — extract or derive (insights, conclusions, examples) from a source. Similar to draw on but slightly more specific to extraction.
  • The paper draws from interviews with 47 participants.
  • She drew from her own experience in writing the memoir.
  • The conclusions are drawn from longitudinal data.
  • Register: academic-formal. Draw on = use as resource; draw from = extract from a specific source. Often interchangeable but draw from has a slightly more extractive flavor.

Confirming and relating — bear out, bear on, bring to bear

The verbs of evidence, relevance, and applied analysis. All share the verb bear with different particles — and all are formal-academic.

• bear out (separable) — confirm (a claim, hypothesis, prediction); validate through evidence.
  • The data bears out the hypothesis.
  • Subsequent studies have borne out her early findings.
  • The evidence bears the theory out.
  • Twenty years of replication have borne out the original claim.
  • The investigation did not bear out the allegations.
  • Register: formal-academic-journalistic. Very common in research papers and op-eds. Latinate equivalent: confirm, validate, corroborate. The past participle is borne (not born) — borne out by the evidence.
• bear on (inseparable) — be relevant to; have a bearing on (a topic, decision, or argument).
  • This finding bears directly on the question of causation.
  • How does this bear on the broader literature?
  • Several factors bear on the outcome.
  • Register: formal-academic. The verb for stating relevance without claiming proof. X bears on Y means X is relevant to Y but does not yet establish X causes Y.
• bring to bear (separable — usually bring + [resources/analysis] + to bear + on + [topic]) — apply or focus (resources, expertise, evidence) on (a problem).
  • The researcher brings advanced statistical methods to bear on the question.
  • We need to bring all our expertise to bear here.
  • Several disciplines were brought to bear on the puzzle.
  • Register: formal-academic. Elevated, slightly archaic flavor. From military/legal usage (bringing weapons to bear). Common in literature reviews and policy analysis.

Focusing and refining — hone in on, refrain from

The verbs of narrowing focus and abstaining.

• hone in on (inseparable, three-part) — focus precisely on (a target, topic, or problem). Note: home in on is the older/standard form; hone in on is now widely accepted in AmE despite being a folk-etymology shift. Both occur.
  • The investigators honed in on a single suspect.
  • Let me hone in on the central claim.
  • The study hones in on three specific mechanisms.
  • Register: academic-business-journalistic. Some style guides still prefer home in on; in current AmE usage, hone in on dominates and is unmarked in most prose.
• refrain from (inseparable) — deliberately avoid (an action); abstain from.
  • Authors should refrain from speculation beyond the data.
  • Please refrain from interrupting until I finish.
  • The paper refrains from making causal claims.
  • Register: formal-academic. The standard formal verb for abstention. In casual speech: don’t / avoid / hold off.

Referring and alluding — allude to, refer to, refer back to

The verbs of citing, pointing to, and revisiting.

• allude to (inseparable) — refer to (something) indirectly or by implication, without naming it explicitly.
  • The author alludes to the recent scandal without naming the parties.
  • She alluded to her earlier work on the same subject.
  • The paper alludes to but does not engage with the debate.
  • He alluded to a possible conflict of interest, but stopped short of naming names.
  • Register: formal-academic-literary. Crucial distinction from refer to: allude to = indirect mention; refer to = direct mention. Mixing them is a C1 vocabulary error. The noun form allusion (a passing or indirect reference) is heavy in literary criticism (the novel is full of biblical allusions).
• refer to (inseparable) — explicitly mention or direct attention to (a source, person, or topic).
  • The paper refers to three earlier studies on the same topic.
  • Please refer to the table on page 12.
  • He refers to her by her professional title throughout.
  • Register: neutral-academic. Direct, explicit reference.
• refer back to (inseparable, three-part) — direct attention to (something previously mentioned or covered).
  • Let me refer back to the question raised in section two.
  • The discussion refers back to the framework introduced earlier.
  • I’ll refer back to this point in the conclusion.
  • Register: academic-formal. Specific to within-document cross-reference.

Confusion table — academic PVs that get mixed up

Academic-passive constructions

US academic writing alternates active and passive PV forms strategically. The passive foregrounds the noun and backgrounds the agent — useful when the agent is the abstract scholar, the methodology, or the data.

• The hypothesis is borne out by the data. (passive — emphasis on the hypothesis)
• Three factors have been honed in on. (passive — emphasis on the factors)
• The argument is laid out in chapter two. (passive — emphasis on the argument)
• The framework has been built on by subsequent scholars. (passive — emphasis on the framework)
• Multiple data sources were drawn on. (passive — emphasis on the sources)
• Speculation should be refrained from. (passive — academic abstention)

Russian-speaking writers often default to active forms because Russian academic style tolerates active “we” more than US style does. Modern US academic writing has shifted away from heavy passive use (style guides increasingly recommend active for clarity), but PVs in the passive are still common when the agent is the data, the methodology, or the discipline as a whole.

Register awareness

Academic PVs sit primarily in formal-to-mid registers.

The C1 academic style is to mix tiers: use build on, draw on, lay out in your introduction; reach for bear out, refrain from sparingly in the discussion; reserve set forth, expound on, bring to bear for moments that warrant elevated diction.

Stance markers — what each academic PV signals to the reader

In academic writing, each PV does specific rhetorical work — it tells the reader where the author stands relative to prior work, the evidence, and the argument. C1-level academic reading is partly about decoding these stance markers in real time.

• build on / draw on / draw from — positioning markers. They tell the reader: I am part of this tradition, my work continues this lineage. Used heavily in introduction sections.
• bear out — evidence-confirmation marker. It says: the data supports this claim. Often paired with hedges (the data largely bears out, the data tends to bear out) to soften absolutism.
• bear on — relevance marker. It says: this matters for the broader question, even if I’m not directly addressing it. Used to connect specific findings to general debates.
• bring to bear — applied-analysis marker. It says: I am using these resources/methods to analyze this problem. Common in methods sections.
• hone in on / home in on — narrowing marker. It says: I am zooming in on a specific aspect. Used to transition from broad framing to specific analysis.
• refrain from — abstention marker. It says: I am deliberately not making this claim, even though you might expect me to. Common in discussion sections where the author wants to caveat conclusions.
• allude to vs refer to — citation-precision markers. Allude to signals: I am mentioning this without engaging it directly. Refer to signals: I am explicitly citing this. Indirect vs direct citation has rhetorical weight.
• set forth / lay out — structural markers. They tell the reader: here comes a formal presentation of an argument. Used to signpost the main thesis or framework.

C1-level academic writing braids these stance markers throughout — every paragraph is doing rhetorical work, and the PVs encode that work efficiently.

Putting it together — academic introduction paragraph

Here is how a C1-level academic introduction might thread these PVs into native-sounding prose.

This study builds on three decades of research into adolescent decision-making, drawing on both longitudinal panel data and a new wave of in-depth interviews. We lay out a revised framework in section two and set forth four hypotheses that bear directly on the question of risk perception. By bringing recent neuroimaging findings to bear on classic behavioral economics models, we hone in on the specific cognitive mechanisms that earlier studies have alluded to but not fully tested. The discussion in section five refers back to the framework introduced earlier and refrains from causal claims beyond what the data bears out. Where the evidence is suggestive but not conclusive, we point to it explicitly rather than gloss over the ambiguity.

Twelve academic PVs appear in this single paragraph — builds on, drawing on, lay out, set forth, bear on, bringing to bear, hone in on, alluded to, refers back to, refrains from, bears out, point to, gloss over. A C1 reader should parse this paragraph at native speed and feel the stance work each verb is doing. A B2 reader would likely substitute Latinate verbs and lose the rhythm.

Common collocations and patterns

• set forth + argument / case / proposal / hypothesis / claim
• lay out + framework / argument / plan / case / structure
• write up + results / findings / report / dissertation / paper
• expound on + theory / idea / point / implications / argument
• build on + work / research / framework / findings / foundation
• build out + structure / methodology / argument / prototype / chapter
• draw on + sources / data / experience / research / literature
• draw from + interviews / data / case studies / archives / examples
• bear out + hypothesis / prediction / claim / suspicion / evidence
• bear on + question / issue / decision / debate / argument
• bring to bear + expertise / methods / resources / evidence + on + [topic]
• hone in on + target / claim / mechanism / factor / question
• refrain from + speculation / commentary / generalization / claims
• allude to + work / scandal / event / debate / theory (indirectly)
• refer to + source / table / page / study / work / person (directly)
• refer back to + point / question / framework / discussion (previously mentioned)

Common Russian-speaker mistakes

1. Using utilize everywhere instead of draw on / use. Utilize is correct but overused by ESL writers. Native academic English alternates: we drew on three data sources, we used a mixed-methods approach, we employed regression analysis. Utilize is fine occasionally but a tell when repeated.
2. Confusing allude to (indirect) and refer to (direct). The author alludes to Smith (2019) is wrong if Smith is cited explicitly — that’s refer to. Allude to is for indirect, implied mention without naming. Mixing them is a C1 lexical error.
3. Saying build up on instead of build on. Russian развивать на основе can produce a calque with up. The correct PV is build on: this study builds on prior work. Build up is a different verb meaning “accumulate” (tension built up).
4. Confusing bear out and bear on. The data bears on the hypothesis (= is relevant to) vs the data bears out the hypothesis (= confirms). Russian speakers sometimes use bear on meaning “confirm,” which is wrong. Bear on = relevance; bear out = confirmation.
5. Saying make a research / make research instead of conduct research / do research / write up research. Russian сделать исследование doesn’t translate as make research. Use conduct research, do research, carry out research for the activity; write up the research for producing the document.
6. Treating expound on as standard. Expound on is elevated; in everyday academic writing, explain, elaborate on, develop are more common. Save expound on for moments of deliberate elevation or extended argument.
7. Saying focus in on instead of hone in on / home in on / focus on. Focus in on is non-standard. Use focus on (neutral), hone in on / home in on (idiomatic precise narrowing). Don’t combine.
8. Using make reference to when refer to would be cleaner. Make reference to is technically correct but verbose. Refer to is the standard academic verb. The paper refers to three studies is better than makes reference to.

Summary

• About 16 academic and research PVs that give US academic prose its stance-signaling rhythm.
• Presentation: set forth, lay out, write up, expound on — articulating arguments and documents.
• Building on prior work: build on, build out, draw on, draw from — citation and source-use.
• Confirmation/relevance: bear out (confirms), bear on (is relevant to), bring to bear (apply to).
• Focusing/abstaining: hone in on / home in on, refrain from — narrowing and avoiding.
• Referring: allude to (indirect), refer to (direct), refer back to (within-document cross-reference).
• The C1 academic style mixes Germanic-particle PVs (build on, draw on, bear out, hone in on) with Latinate concept verbs (analyze, demonstrate, postulate) for rhythm and stance.
• The Russian-speaker trap is over-Latinizing — every PV becomes utilize, demonstrate, focus, elucidate. The result is correct, abstract, and flat. Keep the PVs; they carry the academic voice.
