How do you spell key sleeves on a job application? You almost certainly mean key skills — a common voice-search or autocorrect mistake. The section heading should read Key Skills or Core Competencies. For the phrase describing your abilities, write skill set as two words on formal US documents, per Merriam-Webster.
This page is a spelling reference for resume and application documents — not a skills writing guide. For what belongs in the section, see how to find the right resume keywords . For formatting the block, see best resume section order for ATS . Below: the Resume Term Spelling Reference Card, common misspellings that break ATS matching, and before/after fixes.
Key Takeaways
- Key sleeves → key skills (voice/autocorrect error)
- skill set (two words) is the standard formal spelling
- resume and résumé are both acceptable in US English
- Tool-name typos break keyword matching more than style choices
- Match US vs UK spelling to the posting location
- Copy exact title spellings from the job ad when applying
How do you spell key sleeves? Voice-search and typo patterns
Voice assistants and phone keyboards mishear "skills" as "sleeves" because the consonant clusters sound similar in fast speech. Autocorrect then locks the wrong word. The search intent is still about the skills section on a resume or application — not clothing or keyboard accessories.
Merriam-Webster defines skill set as "the set of skills of a person or group." That is the phrase you want in cover letters and summaries when describing your abilities — not key sleeves, skillset as one word (informal), or skill-set with a hyphen unless the posting uses that form.
Common misconception: spelling does not matter because ATS uses fuzzy matching. Some systems do tolerate minor typos; many do not on exact tool names and certifications. Treat spelling as a matching requirement for hard skills, not a style preference.
Limitation: this guide covers US English job documents. UK, EU, and academic CV conventions use different title and section labels.
Key Takeaway: Key sleeves is almost always a voice or autocorrect error for key skills — change the heading, then spell-check tools.
Resume Term Spelling Reference Card
Use this table as the original asset for this page — bookmark it before you finalize any application packet. Correct form is the left column; the right column shows what fails or looks unprofessional.
| Term | Correct form (US formal) | Common error | Notes |
|---|---|---|---|
| Skills section heading | Key Skills / Core Competencies | Key sleeves, Key skill's | Not a possessive — no apostrophe |
| Ability phrase | skill set | skillset, skill-set | Two words per M-W |
| Job document | resume or résumé | resumé, ressume | Both accent forms acceptable |
| Academic document | curriculum vitae (CV) | curriculum vite, CV vitae | Full phrase on first use in academia |
| Work history | work experience | working experience | Standard US section label |
| Education credential | Bachelor of Science (B.S.) | Bachelors of Science | No apostrophe on degree name |
| Software names | Salesforce, JavaScript, HubSpot | Sales force, Javascript | Copy vendor capitalization exactly |
| Certifications | PMP, AWS Certified, CPA | P.M.P., Aws certified | Match issuer's official string |
Purdue OWL's resume resources treat consistent formatting and error-free text as baseline professionalism — spelling errors in the first screen are among the fastest rejection triggers for human reviewers.
Key Takeaway: Use the left column as the formal US form. Copy vendor and issuer strings exactly for tools and certifications.
Which spelling errors actually break ATS matching
Not every typo carries equal weight. Section headings with minor style variation usually still parse. Hard-skill strings, certification codes, and product names need exact matches on many systems because recruiters set keyword filters to the posting language.
- High risk: misspelled software (Tableu, JIRA vs Jira when posting says Jira)
- High risk: certification abbreviations (PMP vs P.M.P. when posting says PMP)
- Medium risk: skill set vs skillset — usually still readable
- Low risk: resume vs résumé — both recognized
- Human-only risk: key sleeves as a heading — signals carelessness even if ATS ignores it
Run your draft through HireFlow's ATS checker and confirm tool names from the posting appear verbatim in extracted text. If the checker drops a term, spelling or formatting — not the word choice — is usually the cause.
Failure mode: fixing spelling only in the PDF while the paste box still carries typos — portals index both separately.
Key Takeaway: Exact tool names and cert codes fail keyword filters more often than skill set vs skillset.
US vs UK spelling on the same document
Pick one convention and hold it through the entire packet. US postings expect -ize endings (organize, optimize) and -er endings (center, labor). UK postings expect -ise and -re (organise, centre, labour).
When a US company posts a role in London, read the location line and sample sentences in the ad. If the posting uses "programme" and "analyse," mirror that. If it uses American forms throughout, do not mix British spellings because your university used them.
Remote roles that list a US legal entity but a UK hiring manager still follow the posting language. If the ad uses organize, optimize, and center, keep those forms even if you currently live in Manchester. Mixing both on one page reads as unfinished editing.
When this advice does not apply: bilingual applications where the employer explicitly requests two language versions — each file follows its own spelling rules; do not blend them in one document.
Key Takeaway: Pick US or UK spelling from the posting location and hold it through the whole packet.
Three before/after spelling fixes on real resume lines
Illustrative examples — copy the correction pattern, not the industry.
| Before (error) | After (corrected) |
|---|---|
| Section header: "Key Sleeves" — bullet list of tools | Section header: "Key Skills" — same tools, spell-checked |
| "Broad skillset in data analysist and Power-BI dashboards" | "Broad skill set in data analysis and Power BI dashboards" |
| "Certified P.M.P.; proficient in Sales force CRM" | "PMP certified; proficient in Salesforce CRM" |
Key Takeaway: Fix the heading, then the ability phrase, then vendor names — in that order — before you upload.
Pre-upload spelling checklist
- ☑Section headings: Key Skills, not key sleeves or possessive forms
- ☑skill set: two words in summary and cover letter
- ☑Tool names: match vendor spelling from official sites
- ☑Certifications: copy exact abbreviation from issuer
- ☑US/UK: one convention throughout
- ☑PDF copy test: select-all from export — no garbled characters
- ☑ATS extract: confirm posting keywords appear in parsed output
For accent and special-character issues on US resumes, see accented characters and ATS parsing .
Key Takeaway: Section headings, skill set as two words, vendor spelling, and a PDF copy-paste test before submit.
Sound-alike errors beyond key sleeves
Key sleeves is the most obvious voice-search error, but applicants hit similar mistakes on other resume lines. Lead vs led, principal vs principle, and affect vs effect appear in summary paragraphs where spell-check does not flag wrong-word errors.
Read each bullet aloud slowly. If you would not say the word in conversation, verify it in a dictionary before it lands on a document recruiters forward to hiring managers.
- Lead (past tense of lead a team) vs led — use led for past leadership
- Principal (main) vs principle (rule) — principal engineer, not principle engineer
- Complement vs compliment — skills that complement a stack, not compliment it
- Ensure vs insure — ensure quality; insure applies to insurance domains only
These are Tier 1 spelling issues — wrong word, correctly spelled — that automated checkers miss. A human reviewer catches them in seconds; fix them before upload.
Add then vs than, accept vs except, and advise vs advice to the same pass. They cluster in summary paragraphs where applicants write faster than they proof. Greenhouse and Lever do not flag them; hiring managers do.
Key Takeaway: Spell-check misses led vs lead and principal vs principle. Read bullets aloud for wrong-word errors.
Standard section headings and their spelling
Consistent headings help parsers map content to fields. Use title case or ALL CAPS consistently — not both on the same document.
| Section | Preferred US label |
|---|---|
| Skills block | Key Skills, Technical Skills, or Core Competencies |
| Experience | Professional Experience or Work Experience |
| Education | Education — not Educational Background unless space requires |
| Summary | Professional Summary or Summary — not Profile Summary and Summary on same file |
Key Takeaway: Use one conventional label per section and one capitalization style for the whole file.
Software and certification spelling on ATS-heavy resumes
Tool names are proper nouns — copy them from vendor documentation, not from memory. JavaScript is camel-cased with a capital S. PostgreSQL is one word. HubSpot uses a capital S in the middle. When the job posting spells a tool one way, mirror that version in your skills section even if the vendor logo uses another.
Certifications follow issuer rules: PMP without periods, AWS Certified Solutions Architect with capitals as Amazon lists it, CPA as a post-nominal after your name or in a certifications line — not C.P.A. unless the posting uses periods.
Build a personal reference list of every tool and cert on your resume. Update it when vendors rebrand — Facebook Ads became Meta in marketing copy, but job postings may still say Facebook Ads through 2026. Match the posting for matching; match the vendor for general accuracy when the posting is silent.
Workday importers and Greenhouse parsers both tokenize on spaces and punctuation. A stray hyphen in Power-BI when the posting says Power BI can drop the match even though a human would treat them as the same tool.
| Often misspelled | Correct form |
|---|---|
| Javascript, java script | JavaScript |
| Powerpoint, Power Point | PowerPoint |
| Sales force, Saleforce | Salesforce |
| Quick books | QuickBooks |
| SAP HANA as sap hanna | SAP HANA (copy posting if abbreviated) |
Key Takeaway: Mirror the posting for matching; use the vendor’s official string when the posting is silent.
Spelling on cover letters tied to the same search
Searchers who misspell key skills on Google often misspell the same terms on cover letters. The letter is shorter — one typo in paragraph one is more visible than one typo in a twelve-line skills block. Run the same reference card on the letter after the resume passes extract review.
Salutation spelling matters for human readers: verify the hiring manager or recruiter name from LinkedIn or the posting. Dear Hiring Manager is acceptable when no name is published; Dear Sir/Madam is outdated for US corporate letters.
For cover letter structure after spelling is clean, see cover letter format that does not get ignored .
Key Takeaway: One typo in a four-paragraph letter is more visible than one typo in a skills list. Re-check the letter last.
How voice search creates key sleeves and similar typos
Phone keyboards and assistants collapse key skills into key sleeves because the vowel and sibilant patterns are close in fast speech. The same pass can turn skill set into skillset when autocorrect prefers a closed compound.
Dictate the skills section, then read the heading on screen before you export. If the heading is not Key Skills, Core Competencies, or Technical Skills, fix it before any ATS upload. Greenhouse and Workday do not need a fancy heading — they need a conventional one.
Key Takeaway: After any voice-to-text draft, inspect the skills heading first. That is the line searchers misspell and parsers still map.
Verify spelling in parsed output
Spell-check catches obvious typos; ATS extract review catches formatting that hides correct words. Upload your resume to HireFlow's ATS checker and confirm every must-have term from the posting appears in the text the system reads.
Frequently asked questions
No. Searchers typing 'key sleeves' almost always mean key skills — a voice-search or autocorrect error. The correct heading is Key Skills or Core Competencies. Spell skills correctly; ATS parsers match exact strings from job postings.
Merriam-Webster lists skill set as the standard open compound. Skillset appears in casual business writing but looks less polished on formal documents. For US resumes and cover letters, use skill set.
Both resume and résumé are acceptable in US English. Merriam-Webster includes resume without accents as the primary US form. Accents are optional — consistency matters more than which version you pick.
Yes, when the typo changes the word. 'Managment' will not match 'management' on many matchers. 'Skillset' vs 'skill set' usually still parses, but misspelled tool names — 'Salesfroce' for Salesforce — fail keyword checks.
Curriculum vitae is the full Latin phrase; CV is the standard abbreviation. In US corporate hiring, resume is the usual term. Use CV only for academic, research, or international postings that request it.
Match the posting and employer location. A US company posting in Chicago expects organize, analyze, and center. A UK posting expects organise, analyse, and centre. Mixing both on one document signals carelessness.
Copy the exact form from the job ad when it appears in a title field. Full-stack developer, full stack developer, and Full Stack Developer may all appear in postings — mirror the version in the announcement for title-match fields.
Run spell-check in your word processor, then copy-paste the resume text into a plain editor and read every skills line aloud. Export PDF and select-copy each section — if a word breaks oddly, fix it before upload. Run HireFlow's ATS checker to confirm tool names extracted correctly.
