Is there a list of the primitives from RTK1 that are actual kanji in RTK3, for example scorpion: 也 as a primitive in RTK 1 is "est" in RTK3 as a Kanji on it's own, similarly with a bunch of other primitives, augury, comb, zoo, towel etc.

Does anyone have such a list? I've tried searching the forum, but no results.

List and link to tables here thanks to Katsuo.

Great! Exactly what I was looking for, how did I miss this when I was searching.

A good place to start for any type of kanji list is the stickied topic Lists in the General Language section. Katsuo's many lists are there as well as links to various lists other people have created (Wikipedia freq etc.) Thanks again to the contributors.

Mind you, none of the lists I made includes exactly what you are looking for; the nearest ones contain primitive combinations, i.e. not one-to-one primitive to keyword equivalents.

The book itself (RTK3) has one section where it collects them together, from numbers 2090 to 2105. If you have worked through RTK1 and are therefore familiar with the primitives it will be easy to make your own list.
