usually written using kana alone

rarely used kanji form

obsolete kanji
- Kanji that's considered too old to be used nowadays.
search-only kanji form
- The word has kanji which are not shown but are used for search. For example, 落とす has 2 visible forms: 落とす, 落す, but if you search for 堕とす or 墜とす, you will also reach the same word even if they are not visible.
