Food, personnel and staff的文法

PERSONNEL is uncountable and plural. It refers to the people who work in a company, organization, or military force. It can also mean the human resources department of a company.

e.g. All personnel are to receive security badges.

STAFF is the people who work for an organization. It is a countable noun. In British English, staff is often used as a plural noun and followed by a plural verb. In American English, staff is not often used in this way, and is never followed by a plural verb.

e.g. All the staff are very helpful.

The plural form “staffs” is less frequent but is used to refer to more than one group of people: the senator and his staff (singular); senators and their staffs (plural).

FOOD is always uncountable. It is nearly countable only when it refers to a particular kind of food. e.g. health foods, processed foods.

The food is tasty.

It is a question about the singular or plural form of a word.

Food: Singular/Plural = food (is)

Personnel: Singular/Plural = personnel (is)

Staff: Singular/ Plural = staff (is)

For " staff", it can be followed by "are" as well.
