Different between 力強い with 強力 I found an interesting word in a box kind of stamina drugs which said (chikaradzuyoi) which means powerful. The interesting thing for me is, I noticed the word may be interchangeable, like with (kyouryoku) which means powerful too, and I mostly use rather than. Is this a colloquial matter? Or nuance?
