okay...these are the same pronounciation, same spelling. well i can't say that it's always the same. but what i know from my dad is these:

kumo-clouds or
kumo-spider

ame-candy or
ame-rain

This one is a bit diff.

Undokai-sports
Un, dokai?- yes? How was it?

Well don't be confused.....its easy just try to understand it
