🧭 Overview
🧠 One-sentence thesis
Abstract writing requires careful attention to length constraints, strategic word choices (especially pronouns, verb tenses, and modals), and selective citation practices to create a concise, self-contained summary that bridges the title and the full manuscript.
📌 Key points (3–5)
- Length varies by context: journal abstracts typically range from 150-250 words, while conference abstracts may be longer (~500 words), and some formats use very short abstracts (~50 words).
- Word choice is driven by function: the abstract's purpose determines language decisions, including pronoun use, verb tense selection, and modal verb choices that signal certainty levels.
- Verb tense patterns matter: abstracts typically begin and end in present tense, with past tense often used for methods and results, though present tense can strengthen claims about findings.
- Common confusion about citations: while many sources say "never cite in abstracts," citations may be necessary when responding directly to specific research, using coined terms, or conducting replication studies.
- Best practice for drafting: include every important word from the title in the abstract and follow the IMRD/C order to maintain coherence with the full article.
📏 Length requirements and constraints
📏 Typical word counts by format
The excerpt identifies three main length categories:
| Format | Typical Length | Notes |
|---|
| Unstructured journal abstracts | 150-200 words | Without subheadings |
| Structured journal abstracts | ~250 words | With headings |
| Conference submissions | ~500+ words | Disciplinary differences allow longer formats |
| Short communications (IEEE) | ~50 words | Specific article type in certain journals |
🎯 Why length matters
- Abstracts are often used as a "gateway into acceptance," especially for conferences.
- The word/character limit is the first thing to determine when writing an abstract.
- Each journal has specific requirements available on their website.
- Although challenging to summarize an entire study in a few hundred words, length requirements are straightforward to follow once identified.
🔤 Word choice strategies
👤 Pronouns: navigating personal references
The excerpt addresses confusion about personal pronoun use in academic writing:
General guidance:
- Third person "they" or "s/he" is widely accepted when writing about others' work.
- Second person "you" is typically avoided.
- First person pronouns (I, me, my, we) show much variation even among expert writers.
Best practice recommendation:
- Use "they" as the most frequent and acceptable choice regardless of number (singular or plural) or gender.
- This pronoun can have antecedents that are male, female, singular, or plural.
- Most style guides advise against first and second person pronouns and the singular masculine "he."
Don't confuse: The singular "they" is not grammatically incorrect—it has been the most frequent personal pronoun for at least two decades and is supported by current writing guidelines.
⏰ Verb tense: signaling time and strength
General pattern:
Abstracts tend to begin and end in the present tense but vary significantly in their mid-sections.
Tense by section:
- Purpose/background: often past tense
- Methods: often past tense
- Results: often past tense
- Generalizability or significance: present tense to boost importance
Strategic tense choice:
The excerpt provides a comparison showing how tense affects stance:
- Past tense: "Our results showed that there were significant differences between the two types of X."
- Present tense: "Our results show that there are significant differences in the two types of X."
The second sentence presents a stronger stance because present tense is typically used for facts, general truths, or fixed circumstances, while simple past tense indicates actions that may not continue into the present.
Example: When you want to emphasize that findings have ongoing relevance, choose present tense; when describing what was done in a specific study, use past tense.
🎚️ Modal verbs: expressing certainty levels
Modal verbs indicate stance; they allow the writer to strengthen or weaken a claim.
The nine modal verbs:
can, could, may, might, should, must, had better, ought to, will/shall
Why modals matter:
- Each verb carries a level of certainty or doubt.
- They are useful tools for hedging or boosting claims about findings.
- The abstract is crucial for representing your work, so careful modal use is essential for striking the right tone regarding confidence level.
- Other words (adverbs and adjectives like "possibly/possible" or "obviously/obvious") can also indicate tentative or confident stances.
Don't confuse: Modal verbs are not just grammatical requirements—they are strategic choices that communicate your level of confidence in your claims.
📝 Grammatical patterns in abstracts
📊 "That" clauses for reporting results
A 2005 linguistic study of over 200 abstracts from six disciplines found:
Key finding:
Writers tended to use "that" clauses when writing about their results.
Examples:
- "The study's results indicate that..."
- "The findings confirm that..."
Usage patterns:
- In full articles: used in Introduction to review literature ("Other studies have shown that...") and in Results section
- In abstracts: primarily used to highlight findings, not to review literature in detail
🗣️ Common reporting verbs
The excerpt provides a table of highly-frequent reporting verbs often used with "that" clauses:
| Category examples | More examples | Additional examples |
|---|
| describe, show, reveal | study, demonstrate, note | point out, indicate, report |
| observe, assume, claim | assert, examine, state | believe, mention, reveal |
| argue, discuss, find | suggest, focus, provide | propose, reveal, write |
Important considerations:
- Each verb has its own level of certainty (e.g., "assert" is more confident than "indicate").
- Verbs can be combined with adverbs (e.g., "possibly," "certainly") and/or modal verbs to strengthen or weaken claims further.
- Writers should be familiar with the exact meaning of each verb before using it.
📚 Citation practices in abstracts
🤔 The citation debate
Common advice (internet majority): Do not cite sources in abstracts.
Reasons given for avoiding citations:
- To focus on your work, not someone else's
- To present a self-contained work without need for outside reference
- To reduce unnecessary words given the small word count limit
✅ When citations may be necessary
Despite common advice, the excerpt identifies situations where citations are appropriate:
- When doing research that is a direct response to another researcher's findings, theories, or claims
- When using a little-known term coined by someone in particular
- When conducting a replication study or meta-analyses
🎯 Best practice recommendation
The best practice is not to cite sources in an abstract unless it is absolutely necessary.
How to decide:
- Read the Instructions for Authors for your target journal
- If no guidelines exist, examine abstracts of previously published papers in that journal
- If still unclear, contact the editor
Don't confuse: "Academic writing is often not black and white, wrong or right, no or yes"—the citation question depends on context, discipline, journal, and the specific nature of your research.
🔗 Connecting abstract to full article
🌉 The abstract as a bridge
One best practice is to include every important word from the title in the abstract.
Why this matters:
- The abstract's placement and function within a research article is to bridge the title and the text of the manuscript
- This helps you consider the content of the abstract appropriately
📋 Following IMRD/C order
General pattern:
Abstracts present information in the same order as the research article: Introduction, Methods, Results, Discussion/Conclusion.
Note about the final section:
- The conclusion section (Goal 5) may or may not be included based on what stage the research is in
- Many researchers write abstracts prior to completing their studies, making it difficult to explain what findings mean
- Regardless of whether conclusions are included, the abstract will flow in this general IMRD/C order
🎨 Flexibility within guidelines
The excerpt emphasizes throughout that:
- There are "not rules to follow, but rather choices you can make" about what language to include or exclude
- Variations exist at the level of writer, journal, and discipline
- The information provided consists of suggestions based on linguistic research and general academic writing standards, not prescriptive rules
