匂い (におい) refers to a fragrance, or something that is nice-smelling. As far as
I know, this kanji is only used for this word in Japanese.

I notice that the character 匂 is uncommon. The usage of 匂 is rare even in
Chinese, where it is a variant of the character 匈. 匈 is used to refer to the
ancient Huns, or modern-day Hungarians. It was originally used to refer to the
chest area of a human, before being replaced by 胸.

How are Hungarians or chests related to a fragrant smell?

question
kanji etymology
What does the 匂 in 匂い mean?
This [page](https://www.kanjipedia.jp/kanji/0005427300) states:

> 国語で、おもむき（余韻〈韵〉）を「におい」ということから、韵の省略形の勻(いん)の字形を変えたもの。

I had to find the proper glyph to copy from searching 余韻.
