Question

He is the only son of his parents.the word only is

Answer 1

Answer:

Explanation:

I was talking to my English teacher and I introduced myself, saying "I'm an only son." because I have no siblings, the teacher corrected me by saying "only child, not only son."

I wonder if that is true, do we not say "only son/daughter"?

If I was a girl and had no siblings, does it mean I could not say "I'm an only daughter", but have to say "I'm an only child." instead?

Would it be weird for an adult to say "I'm an only child."??

What do you think?

Thank you!
