Is it "a nurse is someone who always helps sick people." or " a nurse is someone which always helps sick people."?

  • "That" will work (as will "who"), but not "which".

1 Answer 1


We use the pronoun 'who' about people (and sometimes pet animals), and 'which' with animals and inanimate objects ('things').

A nurse is a person who helps sick people.

A stick is a piece of wood which is long and thin.

Relative pronouns (Cambridge Dictionary)

  • I do wish that dictionaries like the Cambridge would refrain from calling relative "that" a pronoun, when in fact it's a subordinator (subordinate conjunction).
