I am familiar with the set phrase 「言われてみれば」 as a way to say "Now that you say that", but as I examine the phrase further, the phrase structure strikes me as strange. The 〜てみる conjugation is commonly used to say "to try doing something", but what meaning does it give when used with passive verb form; "to try being done" does not make much sense to me.
Maybe one might argue that 「言われてみれば」 is a set phrase so I should just accept it as such, but when I googled around I found that while many verbs yielded zero results when I tried to find their [passive]てみれば forms, there are some verbs, mostly related to speech, that can use this form:
But there are also some verbs that are not related to speech:
愛されて壊されてみれば (song lyric)
So, in general what meaning does this form give to the original verbs, and in what kinds of scenarios is it used for?
