3. Definition Section

3.1. What Is “Personnel”?

“Personnel” is a noun referring to the people who work for an organization or are engaged in a particular activity. It is most frequently used to denote a group of employees, workers, staff, or members within a business, military, or other formal setting.

The word originates from the French personnel (meaning “staff”), itself derived from personne (“person”). In English, it has been in use since the early 19th century, primarily in military and official contexts.

Grammatical classification: “Personnel” is an uncountable noun (also called a mass noun) and is considered a collective noun—it refers to a group rather than an individual.

3.2. “Personnel” as a Collective Noun

A collective noun refers to a group of people or things considered as a single unit. Examples include staff, team, committee, and police.

“Personnel” fits this category because it describes a group of people working for an organization. Like other collective nouns, “personnel” can sometimes take a singular or plural verb depending on whether the group is seen as a unit or as individuals (with regional variation).

3.3. Pluralization in English: A Brief Overview

Most English nouns form their plural by adding -s or -es (book → books, box → boxes). However, collective or uncountable nouns often do not follow this pattern. Words like staff, clergy, and personnel are already plural in meaning and typically lack a standard plural form.

For example:

  • staff (not “staffs” for people; “staffs” exists but means “sticks”)
  • police (not “polices” for people)
  • personnel (not “personnels”)

3.4. Contexts of Use

Business/HR: Refers to employees or workforce of a company. E.g., “The company is hiring new personnel.”

Military/Defense: Refers to soldiers or military staff collectively. E.g., “Military personnel must follow strict protocols.”

Academic/Research: Refers to staff or faculty members. E.g., “All academic personnel should attend the meeting.”

Other Organizational Contexts: Any organized group (e.g., medical, technical, administrative).

4. Structural Breakdown

4.1. Is “Personnel” Singular or Plural?

“Personnel” refers to a group and is grammatically plural in most cases. However, because it is an uncountable noun, it does not have a distinct singular form and generally takes plural verbs, especially in British English.

Context Example Verb
Business The personnel are required to wear uniforms. Plural
Military All military personnel have received training. Plural
Academic The academic personnel were invited to the seminar. Plural

4.2. Can “Personnel” Be Pluralized?

No. The form “personnels” does not exist in standard English. “Personnel” is already plural in meaning and is treated as a collective noun; adding an -s is incorrect.

Dictionaries (such as Merriam-Webster, Oxford, and Cambridge) and language corpora (such as the British National Corpus and the Corpus of Contemporary American English) do not recognize “personnels” as a correct form.

4.3. “Personnel” vs. “Person” vs. “People” vs. “Persons”

Term Singular/Plural Definition Example
person Singular An individual human being One person is waiting outside.
people Plural More than one person; general plural of person Many people attended the event.
persons Plural (formal/legal) Legal or formal plural of person Only authorized persons may enter.
personnel Collective (uncountable) Employees or members of an organization All personnel must sign in.

Use “personnel” when referring to the group of employees or members, not to individuals.

4.4. Subject-Verb Agreement with “Personnel”

In most cases, “personnel” takes a plural verb:

  • Correct: The personnel are on duty tonight.
  • Incorrect: The personnel is on duty tonight. (except in some US English contexts where collective nouns may take singular verbs)

See Table 2 in the Examples Section for more.

4.5. Modifiers and Quantifiers with “Personnel”

“Personnel” is often used with quantifiers and determiners such as all, some, many, few, the, any. It is not used with a/an because it is uncountable.

a/an No *A personnel was absent. (Incorrect)
the Yes The personnel are ready.
each No *Each personnel should arrive early. (Incorrect)
several Yes (but rare; often “several members of personnel”) Several personnel have been promoted.

4.6. Countability and Measurement

“Personnel” is uncountable. To express numbers, use a quantifier or specify the number of members or personnel (e.g., “200 personnel,” “members of personnel”). You cannot say “one personnel” or “two personnels.”
