Why should one use the dictionary form instead of the potential form in this case?


The question:

> 映画が好きなので、時間とお金が ＿ 限り見に行っている。

Both "許す" and "許せる" are offered as choices, and the answer is "許す".

Is it because "時間とお金" are impersonal, so the potential form "許せる" would not be
appropriate here?




Do you have a reason for thinking the potential form should be correct?

I think the answer is no deeper than, that's just what people say. The
potential form would be grammatical but unnatural. Just like in English, you
would naturally say "if time permits" but saying "if time is able to permit"
would sound really weird.
