[Lingo] 遅過ぎる

[s smith <sjs@example.com>]

Hi All.

I stumbled on 遅過ぎる while looking for something else.  I think it's 
pronounced 「おそすぎる」, at least that's what the IME takes to create 
the kanji. 　It doesn't show up in the on-line dictionaries I use as a 
word but Eijiro recognizes it as meaning "too late".  I know that 「過ぎ 
る」 can be used as a suffix meaning basically "too much."    But what 
is going on here?  Is this　「遅い」 minus the 「い」 + 「すぎる」 or 
what?  Is there a pattern here for い adjectives or is this just a 
special case?  Would "too beautiful" be 美し過ぎる?  The IME seems happy 
with that.

Thanks
