I was looking for a list of joyo kanji and want to study just their writing and definition but wasn't having any luck. Is it possible to take the Reviewing the Kanji lists and make it so definitions are reviewed are also?

Since the books focus on the characters, those lists only have the writing studied. Those single characters have the general definitions for the characters and on and kun readings, so they're not able to be studied. They don't represent words that are used, just the characters themselves.

Could make a new list, taking those characters and adding them as words instead of components, where the characters stand alone as words anyway.

The reason we don't have study for component definitions and on and kun readings is because they're not very useful on their own, they're really best learned in the context of whole words.

I got that, and agree, I just want to be prompted to produce the keyword too so I know I got the meaning too. I'm afraid I'm not really getting the meaning if I'm not asked if I know the keyword.
