Sentence craft

Scientific prose becomes easier and more pleasurable to read when sentence structure does more of the guidance work. Do not rely only on transition words.

Topic position and stress position

Readers take cues from where information appears in a sentence.

Topic position

The start of the sentence should connect to what the reader is already tracking.

Useful starts:

• the object of study
• the experimental condition
• the specific comparison
• the previously established result that the new sentence extends

Weak starts:

• empty scene-setting (Importantly, Notably, In this context)
• vague pronouns (This, These, It) when the referent is not obvious
• long subordinate clauses before the reader knows the subject

Stress position

The end of the sentence naturally carries emphasis. Put the sentence's point there when possible.

Weak:

• We compared treated and control samples, which were processed using our standard pipeline.
• The sentence lands on logistics.

Stronger:

• Using the same processing pipeline for both groups, we found that treatment selectively expanded the resistant subpopulation.
• The sentence lands on the actual finding.

Old-to-new flow

Whenever possible, start with known information and end with the new contribution. This reduces re-reading.

Weak:

• A previously unrecognised state transition emerged in cells exposed to stress, following our high-frame-rate imaging analysis.
• The new analytic method arrives late and blurs the reader's route.

Stronger:

• Using high-frame-rate imaging, we detected a previously unrecognised state transition in cells exposed to stress.

Prefer verbs over nominalizations

Noun-heavy prose is one of the fastest ways to make a manuscript sound machine-written or bureaucratic.

Weak:

• This observation provides support for the interpretation that...
• The regulation of differentiation was mediated by...

Stronger:

• This observation suggests that...
• X regulated differentiation by...

Do not chase this mechanically. Some noun phrases are the correct technical labels. The goal is to remove unnecessary hidden verbs.

Break present-participial clause chains

Instruction-tuned models often overuse -ing clause chains.

Weak:

• Using live imaging, revealing a previously hidden transition, and suggesting a mechanism for resistance, we...

Stronger:

• split into 2-3 sentences
• give the main clause a clear verb
• keep the -ing form only when it truly improves flow

Active and passive voice

Prefer active voice when it clarifies agency.

• We measured, we trained, we compared, we estimated

Use passive voice when agency is irrelevant or the object deserves sentence-initial focus.

• Samples were fixed in 4% paraformaldehyde
• Cells were imaged every 5 min

The problem is not passive voice itself. The problem is habitual passivity that hides who did what or drains energy from claim-bearing sentences.

Tense discipline

A workable default:

• past tense for what you did and observed
• present tense for what figures show in the paper now, and for general truths
• cautious present or modal language for claims that extend beyond direct observation

Do not let tense drift randomly.

Manage acronyms and symbol load

• define only the acronyms that truly save space or prevent repetition
• avoid stacking multiple undefined abbreviations in a single sentence
• if the paper needs heavy symbol use, slow down the first appearance and orient the reader explicitly

Rhythm and variation

Human scientific prose usually mixes:

• short claim sentences
• medium explanatory sentences
• occasional longer synthesis sentences

A draft where every sentence has nearly the same length feels automated even when each sentence is individually fine.

Good variation does not mean ornamental style. It means the sentence length matches the job.

Punctuation

• use commas to reduce ambiguity, not to create faux complexity
• use semicolons sparingly and only when they genuinely compress related material
• use em dashes rarely; overuse reads mannered
• colons work well when a sentence sets up a list, contrast, or consequence

Line-edit questions

When a sentence feels wrong, ask:

1. What is this sentence trying to do?
2. Does the subject appear early enough?
3. Does the main verb do real work?
4. Does the sentence land on the point that matters?
5. Can one clause become its own sentence?
6. Is the key noun hidden inside an abstract phrase?

Quick repair patterns

Replace empty significance language

• These findings highlight the importance of X
• These results show that X constrains Y under Z conditions

Replace throat-clearing

• It is important to note that
• delete it, or say the actual point

Replace vague demonstratives

• This suggests
• This increase in chromatin accessibility suggests

Shorten stacked modifiers

• high-resolution time-resolved single-cell transcriptional profiling framework
• distribute the information across the sentence instead of forcing it into one noun pile
