I have a question.?

Question

Katherine Brynat joined Purcell Firm forty years ago, making her one of our longest-serving employees since the firm was first established.

i'm a foreigner.

In this sentence , "her"

Why reflexive pronoun is not used ?

Answer 1

The reflexive pronoun is used primarily either for emphasis (she herself bought bread) or as the object of a preposition (she bought bread for herself).

Here, we just use the pronoun "her" as a stand-in for the word Katherine, since it was already stated earlier in the sentence. This is what the sentence would say if you did not use the pronoun:

Katherine Brynat joined Purcell Firm forty years ago, making KATHERINE one of our longest-serving employees since the firm was first established.

Katherine is a proper noun, and nouns are always replaced by regular pronouns, not reflexive pronouns.
