Question

what are called pronounce

Answer 1

I think the word you meant maybe "pronouns".
If so,a pronoun is a substitution given to a noun that repeats in other sentences.

For example,
1. Raju is a good boy.
'He' is also smart.
2. I love my cat.
'It' is very cute.

Here, 'he' and 'it' are called pronouns.
