Many people get confused about which version to use, leading to inconsistencies or errors that might make your writing look less polished.

By the end, you’ll understand the differences, know when each form is appropriate, and have practical tools to ensure your writing is professional and precise.
Understanding the Terms
“Skill-Set”
The hyphenated version, “skill-set”, is historically common in professional writing. It emphasizes the compound nature of the word, connecting “skill” and “set” to show they function as a single concept.
Key points:
- Often used in business and HR contexts.
- Seen as slightly formal, but also suitable in resumes or LinkedIn profiles.
- Hyphenation can help clarify meaning, especially in longer sentences.
Example usage:
- “A strong skill-set in data analysis and project management is essential for this role.”
- “Our team’s skill-set allows us to tackle complex challenges efficiently.”
Note: Overusing hyphens can make text look cluttered, so it’s best for specific professional contexts rather than casual writing.
“Skillset”
“Skillset” is the modern, single-word form. It has become increasingly common in business, marketing, and HR documents, particularly in the United States. Many contemporary dictionaries, including Merriam-Webster, now recognize it as standard usage.
Advantages of “skillset”:
- Concise: One word instead of two or three.
- Modern appeal: Frequently used in corporate and tech industries.
- Acceptable in most professional writing: Especially on LinkedIn profiles and CVs.
Example usage:
- “Her skillset includes strategic planning, coding, and team leadership.”
- “Candidates with a broad skillset are more adaptable to changing job roles.”
While widely accepted, some formal style guides still prefer “skill set,” so it’s important to consider your audience.
“Skill Set”
The two-word form, “skill set”, is considered the most formal and traditional. It appears often in academic writing, research papers, and style-guided documents.
Key points:
- Clearly separates the noun “skill” from “set,” making the phrase easy to understand.
- Preferred in APA, Chicago, and MLA style guides.
- Often recommended for formal reports and scholarly work.
Example usage:
- “The researcher’s skill set allowed accurate data collection across multiple experiments.”
- “Developing a diverse skill set can improve your career prospects over time.”
Tip: In formal writing, the two-word version is usually safest. It avoids ambiguity and meets style guide expectations.
Grammar and Style Considerations
Understanding the grammar behind these forms can help you decide which one fits your writing style.
Hyphenation Rules:
- Hyphenate compounds when they function as adjectives before nouns:
- Correct: “A strong skill-set advantage.”
- Incorrect: “The team’s skill set is strong.” (No hyphen needed after the noun)
American vs. British English:
- In American English, “skillset” as one word is becoming dominant in corporate usage.
- In British English, “skill set” is still preferred, especially in formal writing.
Style Guides:
- APA: prefers “skill set.”
- Chicago Manual of Style: allows both “skill set” and “skill-set” depending on context, but generally favors clarity.
- LinkedIn/Business writing: “skillset” is widely accepted for modern corporate tone.
Decision tip:
- Ask yourself: “Who is my audience?” Use “skill set” for academic/professional papers, “skillset” for modern corporate contexts, and “skill-set” sparingly where hyphenation clarifies meaning.
