The Japanese Kanji “萎(い – I orな（える）- na (eru))” has meanings of “wither or weaken”. And the following Japanese character images are some example of Japanese words which contain the Kanji “萎”. This Kanji “萎” is often used one but the words that contain this kanji are not many. I found only following two words.
The Japanese word “萎縮(いしゅく– ishuku)” means “shrink or shrivel”.
The Japanese word “萎靡(いび– ibi)” means ” decline or decay”.
