Etymology 1

Kanji in this term
硫	黄
い Grade: S	おう Grade: 2
jukujikun

Alternative spellings
硫黃 (kyūjitai) 硫磺

/juawa/ → /juwau/ → /iwau/ → /iwɔː/ → /iwoː/ → /ioː/

Originally a compound of 湯 (yu, “warm or hot water”) +‎ 泡 (awa, “bubble”), from the way that volcanic hot springs would often be accompanied by bubbles of sulfur gas.

The kanji spelling is an example of jukujikun (熟字訓), from Chinese 硫黃／硫黄 (liúhuáng).

An alternative theory is that the character 硫 (“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. 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.
