Analyses vs. Analyzes: Choosing the Right Verb Form
Writers trip over “analyses” and “analyzes” every day. The two words look almost identical, yet one is a noun and the other a verb, and swapping them changes the meaning of a sentence.
Google N-gram data shows that the mistaken use of “analyses” as a verb appears in roughly one of every eight online articles about data science. That single slip can undermine an author’s credibility in fields where precision is currency.
Etymology and Core Distinction
“Analyses” comes from the Greek “analusis,” a noun meaning “a breaking up.” It entered English through Latin in the late 16th century and has remained a noun ever since.
“Analyzes” is the natural third-person singular present form of the verb “analyze,” which followed the regular ‑ize suffix pattern that English borrowed from Greek via Latin. The spelling settled in American English by the 18th century, while British English later accepted both “analyse” and “analyze.”
Remembering the part of speech is the fastest filter: if you can replace the word with “study” and the sentence still works, you need the verb “analyzes.” If you can put “the” in front of it, you need the noun “analyses.”
Memory Trick: Ending Sounds
Say both aloud. “Analyses” ends in “eez,” a soft plural hiss that signals a noun. “Analyzes” ends in “eyez,” a voiced verb ending that echoes other action words like “realizes” and “recognizes.”
When you proofread aloud, the pronunciation difference jumps out. Your ear catches what your eye misses.
Grammatical Roles in Context
“Analyzes” must have a singular subject performing the action. “She analyzes quarterly sales” is correct; “They analyzes” is instantly wrong because the plural subject clashes with the singular verb form.
“Analyses” can serve as subject, object, or complement. “The analyses reveal a trend” uses it as the subject. “We reviewed several analyses” places it as the direct object. “The report is full of analyses” employs it as a complement.
Neither word can switch jobs without breaking grammar. “She analyses the data” is a category error, not a stylistic choice.
Plural vs. Singular Nuances
“Analyses” is already plural; its singular is “analysis.” If you write “analyseses,” you have created a double plural that does not exist. One analysis, two analyses—never add another suffix.
“Analyzes” has no plural; verbs do not pluralize in English. “They analyze” is the plural form, dropping the ‑es entirely.
Academic Writing Conventions
Journal submission systems often flag “analyses” used as a verb with an automatic grammar alert. Editors treat the mistake as a marker of non-native or careless writing.
In APA-style method sections, the expected phrasing is “The software analyzes the recordings,” not “The software analyses the recordings.” Using the noun form forces an awkward passive rewrite: “The recordings undergo analyses,” which costs clarity and words.
Grant reviewers notice. A 2022 survey of NIH panelists showed that 38 % admitted down-scoring proposals with repeated grammar slips, including the analyses/analyzes confusion.
Citation Practices
When you cite a paper, the author’s action is locked into the verb. “Smith et al. analyze” is correct in American journals. If you retain the British spelling “analyse,” keep it consistent throughout the manuscript.
Never let the citation drive your own spelling choice. Match the journal’s style sheet, not the author’s nationality.
Business and Data Science Applications
Dashboard tooltips need the verb. “This widget analyzes churn in real time” tells users what the feature does. Writing “This widget analyses churn” turns the tooltip into a fragment that sounds unfinished.
Slack announcements follow the same rule. “Our new model analyzes 10 k signals per second” reassures stakeholders. Replacing the verb with the noun leaves the sentence without a predicate and creates confusion.
Client-facing slide decks punish the error harder. A single typo on the title slide can redirect attention from quarterly ROI to grammar, wasting the presenter’s first 30 seconds of credibility.
Code Comments and Documentation
Docstrings should read “Analyzes the input array and returns outliers,” not “Analyses the input array.” Python’s Sphinx will parse the verb correctly and generate clean HTML; the noun form breaks subject-verb agreement and may confuse non-English teammates.
Inline comments compound the problem. “# analyses transaction volume” is silent sabotage: the reader mentally supplies the missing verb, then doubts the coder’s precision.
British vs. American Variance
UK English allows “analyse” as the verb, so “she analyses the results” is acceptable in London journals. American English keeps the ‑ize form, so “she analyzes” is required in New York.
The noun is invariant. “Analyses” is the plural everywhere, from Edinburgh to San Francisco. You can switch verb spellings across the Atlantic, but the noun never changes.
Multinational teams need a style consensus. Agree on either Oxford or Chicago up front, then automate enforcement with a linter or CI check so pull requests do not devolve into spelling debates.
SEO Localization Impact
Google’s keyword planner clusters “analyses data” and “analyzes data” into separate volumes. The noun-verb swap can shift search intent from informational to transactional, hurting CTR if the landing page mismatches the query.
hreflang tags must align spelling with regional expectation. A U.S. page targeting “analyzes customer behavior” should not canonicalize to a U.K. page titled “analyses customer behaviour.”
Common Collocations and Idioms
“In-depth analyses” is a stock phrase; substituting “in-depth analyzes” is impossible because adjectives do not modify verbs. “Thoroughly analyzes” works, but “thoroughly analyses” is only valid in British English and still needs a singular subject.
“Meta-analyses” is a fixed technical term. Writing “meta-analyzes” creates a new verb that reviewers will reject.
“Spectrum analyses” is plural, yet many writers drop the plural marker and write “spectrum analyses reveals,” pairing a plural noun with a singular verb. The fix is either “analyses reveal” or switch to “analysis reveals,” depending on how many studies you pooled.
Preposition Pairings
“Analyses of” is standard. “Analyses on” is usually a preposition error introduced by non-native speakers. “Analyzes for” is acceptable when the verb takes a benefactive object: “The algorithm analyzes for bias.”
Check corpus data to confirm collocation strength. COCA shows “analyses of” outpacing “analyses on” 40:1, a ratio worth respecting.
Software and Automation Pitfalls
Grammarly’s default setting flags “analyses” used as a verb only if the document language is set to American English. Switch to British English and the alert disappears, even though the underlying grammar is still shaky in mixed-audience documents.
Google Docs’ spell-checker learns from user input, so a team that repeatedly mistypes the noun can train the model to accept the error site-wide. Reset the dictionary quarterly to prevent drift.
ATS résumé parsers discard keyword variants. If the job ad asks for “analyzes trends,” uploading a CV with “analyses trends” may drop your match score by 5–8 %, enough to bump you out of the first recruiter review batch.
Automated Report Generation
BI tools such as Tableau auto-generate captions. Feed them a template string like “
Version-control the template in Git, not in the UI, so a grammar fix can propagate across hundreds of dashboards with one commit.
Teaching and Testing Strategies
ESL students benefit from color coding. Highlight verbs in green, nouns in blue. Present a sentence pair: “The scientist analyzes samples” vs. “The analyses are complete,” and ask them to tap the green or blue card. The kinesthetic link halves error rates in exit tests.
Corporate workshops should replace blank-fill drills with micro-writing tasks. Ask participants to write a two-sentence Slack update about last month’s data. The tight context forces active choice and surfaces errors while the memory is fresh.
Advanced writers need rhetorical stakes, not grammar rules. Show them a published paper that lost a citation because the reviewer spotted “analyses” used as a verb. Real-world cost motivates better than abstract rules.
Assessment Rubrics
Include a binary “precision” row in peer-review forms. Deduct nothing for first offense, but flag and explain. Learners retain the rule when they must teach it back to the author.
Track repeat errors across assignments. A second offense triggers a five-minute personalized video feedback instead of written margin notes. The spoken channel reinforces the pronunciation cue.
Editorial Workflows and Checklists
Copyeditors should run two passes: a mechanical regex search for “banalysesb” and a semantic pass reading every subject-verb pair. The regex catches 90 % of slips, but only human eyes spot “The group’s analyses reveals.”
Introduce a “grammar owner” in agile docs teams. Rotate the role each sprint so every writer feels the pain of cleaning the final PDF. Ownership reduces collective tolerance for micro-errors.
Store the rule in the style guide as a negative example. State bluntly: “Never use analyses as a verb; use analyzes (US) or analyse (UK).” The imperative voice leaves no wiggle room.
Publication Checkpoints
Just before submission, run a custom script that exports every sentence containing either word to a CSV. Review the column in isolation; stripped of context, the error pops.
Add a GitHub Action that fails the build if any markdown file introduces the noun-as-verb mistake. Continuous integration turns grammar into an engineering requirement, not an editorial afterthought.
Psychological Impact on Readers
Subject-matter experts judge competence fast. A 2021 eye-tracking study found that senior data scientists fixate 200 ms longer on grammar violations, skipping the subsequent numerical content on first pass. The delay erodes persuasive momentum.
Clients interpret the slip as signal noise. If the writer cannot control a basic inflection, what other corners were cut in the model’s hyperparameter tuning? Doubt metastasizes.
The effect is asymmetric: flawless usage goes unnoticed, but one error stains the whole document. The return on editing is therefore front-loaded; fixing the verb is the cheapest credibility boost available.
Trust Repair
If an error ships, correct publicly. A concise erratum—“We mistakenly used ‘analyses’ as a verb; the correct form is ‘analyzes’”—rebuilds trust faster than stealth edits. Readers reward transparency more than perfection.
Pair the correction with a one-sentence takeaway on why the distinction matters. The educational framing converts embarrassment into authority.
