Many thanks, DocV! You have corrected my misunderstanding of xxx-odd and xxx-something.
In Cantonese, we don’t have a specific description of someone who is aged between 10 and 12. If we want to say someone aged about 11, 12 or 13 and probably 14, we can say that he is in his “ten early”. There is no specific reason for asking this question. I asked this question simply because we have the term “teens” and was wondering if there is any description of a person aged between 10 and 13. “Pee-teens” is the word I have learnt from you even though the description may not be very precise.
I like your response to Q4. Do people say “ten-something”?
Q7: I don’t have a specific number in mind. For example, if a pen costs about $50 but the speaker really can’t remember how much it costed. He vaguely remembered that it was less than $100 and may be $30, 40, 50 or 60. I was wondering what the expression should be. Maybe the speaker can say that the pen costed a few dozens of dollars or a few ten dollars.
I have to say thank you again.
