Would you ever use 親友 to refer to your romantic partner?


My understanding is 親友 (shinyuu) is the closest equivalent to English "best
friend." In English, some people might say things like "My husband/wife is my
best friend." Would using 親友 similarly be appropriate in Japanese? I'm not
meaning to refer to them exclusively as this, I know there are other words for
that, but would it make sense to also consider that person your 親友?




I assume you are asking whether calling your spouse a 親友 is completely
unnatural in Japanese or not. The answer is that it is possible to say
夫/妻は親友です.
