in the sentence "This is my cellphone" which part of speech is "my"?
And it is not a part of the speech, it is a function of a sentence..
Um... Function and word type... ol
In short, you'd be right in saying that my is a possessive pronoun and a possessive adjective. One's its form, the other its function.
All the best.
thanks 4 ur rply dis is sumthng new 4 me.i hvnt studied abt possessive pronouns
