"under twenties" means ages between 11 and 19. Using "twenties" is just to emphasize everybody and all with ages between 11 and 19.

Under twenty 照字面講19 嵗或以下的都可以這樣回答。但實際上如果問年紀在國小或13,14嵗的人的年紀,不可能會誤為18,19,嵗的大孩子How old are you?,如果回答I am under 20.那未免有點怪怪。所以也不能亂用。如果說Only all ages of under 20 may come in. 那就可以。Source(s): Self

under twenties 可理解成一時口快而說得不合文法的說法。
