Is there any difference between 大の好物 and 大好物?


This might seem like a ridiculous question, but I heard from a native that
there is an emphasis when using 「大の好物」 instead of 「大好物」. Is this true?

If this is so, why would 「大＋の」 indicate more emphasis on something "more" or
"larger" compared to just placing 「大」 in front of the word?

Can we do this with other words than just 「大」?




According to an entry for the word usage in a Japanese dictionary:

<http://dictionary.goo.ne.jp/leaf/jn2/134173/m0u/>

you could in principle use 「大の」 a bit more liberally to put a larger emphasis
on something.

I agree that the usage of 「大の」 seems to be somewhat limited to a certain set
of words like 好物, 親友, 仲良し, or idiomatic cases like

> 大の大人がいつまでもアニメなんて観てるんじゃないの

(Roughly translates to "an adult at your age should not be watching anime any
more.")

You can also find cases where the usage might not be so prevalent yet still
seems natural, such as 大のおしどり夫婦 and 大のスポーツファン (both of which to me sound
okay). But in other cases they just sound awkward to my ears, like 大の先輩、大の女優,
etc. Although if it were put this way:

> あなたみたいな大の女優がマリファナなんて吸ってるんじゃないの。せめてコカインにしなさい。

(An actress of your stature should not be smoking weed. Go for crack at
least.) then it actually does sound natural to me, likely because this case
follows the idiomatic pattern that I quoted above for 大の大人. So, if you dig
deeper, there might be a way to understand a rule or two about why one sounds
okay but others feel awkward, but asking グーグル先生 didn't yield anything useful
for me to understand this better.
