Is it possible to tell whether a word is kanji or hiragana without reading it?


Is it possible to tell whether a word would be written in kanji or if it would
be written in hiragana without actually reading it, like it is reasonably easy
to tell if a word is likely to be written in katakana? (An example for
katakana would be "this is an English loanword so it's probably written in
katakana")

Background: The kana version of Japanese for Busy People 1 uses only kana - it
doesn't have kanji with furigana, and I'm wondering if not knowing which words
are really hiragana, and which are not really hiragana would be a problem.




Not per se. EDICT has "uk" (usually kana) and "uK" (usually kanji)
annotations, but for the most part either is acceptable.

> 只今 ただいま  
>  (int,exp, **uk** ,abbr,n-t,adv) Here I am; I'm home!; presently; right
> away; right now; just now; (P)
