Personnel means staff or workforce.
Personal and PersonnelThe words personal and personnel sound fairly similar and both derive from the Latin word personalis (meaning personal). However, their meanings are quite different. (Of note, personal is stressed on the first syllable, and personnel is stressed on the last syllable.)
PersonalThe word personal is most commonly seen as an adjective. Generally, it will mean something like private or individual. Here are some more nuanced meanings:
Affecting or belonging to a specific person (as opposed to someone else):
- That is my personal bag.
- Wisdom is what's left after we've run out of personal opinions. (Cullen Hightower)
- It was his last personal appearance.
- My personal hobbies are reading, listening to music, and silence. (Edith Sitwell, 1887-1964)
- He keeps his personal life to himself.
- I don't think I'm obliged to discuss my personal issues with you.
- Nothing endures but personal qualities. (Walt Whitman, 1819-1892)
- He's the reason why I think confidence is an overrated personal trait.
- The biggest issue is his personal hygiene.
PersonnelThe word personnel is most commonly seen as a noun. Personnel is similar in meaning to staff (i.e., it denotes the people employed in an organisation, business, or service).
- The equipment is first rate, but we need more personnel.
- Clever personnel don't make good analysts. Trained analysts make good analysts.
- We have a personnel issue. (i.e., a problem with our staff)
Let the single n of personal remind you it's about one person (i.e., private or individual).
Let the double n of personnel remind you it's about more than one person (i.e., staff or the workforce).
