Etymology 1[edit]

Kanji in this term

Grade: S
おう
Grade: 2
Irregular

/juawa//juwau//iwau//iwɔː//iwoː//ioː/

Originally a compound of ‎(yu, warm or hot water) +‎ ‎(awa, bubble), from the way that volcanic hot springs would often be accompanied by bubbles of sulfur gas.[1][2]

The kanji spelling is an example of jukujikun.

An alternative theory is that the character ‎(sulfur) developed an on'yomi of yu instead of the usual goon of ru or kan'on of ryū, such that the reading is on'yomi.[1] However, given that this particular sound shift is not found in other kanji readings, this derivation seems unlikely.

This is the most common reading for this term in modern Japanese.
