[Lingo] もにのあわる

[steven smith <sjs@example.com>]

Is anyone familiar with this phrase(moninoawaru).  I'm not
sure I have it spelled right and I can't seem to find it in
the dictionaries.  It might be おわる.  I heard it in the
commentary on Ozu's film "Late Spring" and it means
something like "a tragic sense of life."  It seems like many
of the Japanese films I've seen have this feeling and I
wondered what the correct spelling is.

Is this  an integral part to understanding the culture like
for instance the concepts of 本音/建前?

Thanks
