In Japanese, there is a potential form to express that it's possible for something to be done.
My own examples of potential form:
辛【から】い食【た】べ物【もの】が食【た】べられる。 (I can eat spicy foods.)
ギターが弾【ひ】ける。 (I can play the guitar.)
But I also know of
聞【き】こえる. I've heard them used as also meaning it's possible for something to be done (seeing for
見【み】える and hearing for
聞【き】こえる). But this isn't the potential conjugation of the original words,
聞【き】く. The potential form would be
What is the difference between the normal potential form and their "special" forms?
