The word ‘friend’ is primarily a noun.
A noun is a part of speech that represents a person, place, thing, or idea. In this case, ‘friend’ refers to a person with whom one has a bond of mutual affection, typically excluding family or romantic relationships.
For example, in the sentence ‘She is my friend,’ the word ‘friend’ is used to denote a person who has a special connection with ‘she.’ It describes the relationship and social bond rather than an action or a descriptor, which further solidifies its classification as a noun.
