Aaaa it didnt accept "he smokes a cigarette" why
I think this is because it was a general statement of the fact that he is a smoker. Otherwise it would have been かれはタバコをすっています as in he is smoking a cigarette
I doubt many people use this, but some older folks will say 喫む (のむ, same verb as drinking) when referring to smoking cigarettes.
My grandpa (just turned 90) thinks it's more refined.
isn't the kanji for drinking "飲む"?
So, 'He smokes' is acceptable here, but not in previous questions ー_ー
And how do say it when he smokes fish?
