Questions & Answers about Ông ấy lừa tôi.
Yes—ông literally refers to an older man, and it is also used as a respectful way to address or refer to a man.
In Vietnamese, words for he / she / you / I are often based on:
- age
- social relationship
- respect level
- family-style terms
So ông ấy means something like:
- that man
- that older gentleman
- he (when the person is an older man)
It is not a neutral, one-size-fits-all he like in English. Vietnamese usually chooses a pronoun based on who the person is relative to the speaker.
Ấy helps mean that or that one, and in pronouns it often helps create a third-person meaning like he / she / that person.
So:
- ông = an older man / sir / grandfather / Mr.
- ông ấy = that man, which in context often becomes he
You can think of ông ấy as a common way to refer to that older man who has already been mentioned.
Without ấy, ông could sound more like:
- directly addressing him: sir
- or referring to him in a less clearly third-person way, depending on context
