I've read that several bits of Japanese come from contractions with
で + ある(source)
に + ある(source)
て + あり(source)
と + あり(source)
- Adjective forms like
たのしかったcome from inflecting
たのしく + ある(source)
Because contraction with
ある seems to have occurred quite a few times, I started wondering if the suffix
〜がる (as in
ほしがる) was a contraction of
が + ある. I realize this is baseless speculation, but it sounded plausible to me, so I tried to look it up to see if it was right. Unfortunately, I couldn't find anything about the etymology of
がる online, and my dictionaries don't say anything on the subject either.
Is this possible? Is there a better explanation?
