Questions & Answers about Cô ấy tha cho tôi.
A natural breakdown is:
- cô ấy = she / that woman
- tha = forgive, pardon, or spare
- cho = part of the common pattern tha cho + someone
- tôi = I / me
So the sentence structure is basically She forgives me or She spares me, depending on context.
Ấy helps turn a word like cô into a third-person reference: that cô, which is commonly understood as she.
You will see the same pattern in:
- anh ấy = he
- chị ấy = she
- ông ấy = he / that man
- cô ấy = she / that woman
So ấy is not a separate subject like English she. Instead, it combines with a kinship/social term to identify the person being talked about.
