Skill Set or Skillset? Which Spelling Is Correct in Professional Writing?

You are updating your resume. You type, “I bring a strong technical skillset.” Then you stop. Is it skill set or skillset?

Many students, job seekers, and business writers search this keyword because they want to look professional. A small spelling mistake can hurt credibility. Recruiters notice details. Editors notice details. Even grammar tools may flag the wrong form.

The confusion exists because English changes over time. Some two-word phrases become one word. Others stay separate. So people wonder: has skill set become skillset?

Quick Answer

The correct and standard spelling is:

✅ Skill set (two words)

Example:

• She has a strong leadership skill set.
• This job requires a technical skill set.

The one-word form skillset is informal. It is not the preferred spelling in major dictionaries like the Merriam-Webster Dictionary or the Oxford English Dictionary.

If you are writing a resume, academic paper, or business email, use skill set.

The Origin of Skill Set

The word “skill” comes from Old Norse skil, meaning knowledge or ability. The word “set” means a group or collection.

When combined, “skill set” simply means:

A group of abilities a person has.

At first, it appeared as two separate words. Over time, some writers began closing it into one word—“skillset.” This often happens in business language, where short forms feel modern.

However, not all compound words fully merge. Many stay open forever. “Skill set” is still in the open compound stage.
