鬼灯

Probably originally a compound of 頬 (hō, “cheeks”) +‎ 付き (tsuki, “resembling, appearing like”, the 連用形 (ren'yōkei, “continuative or stem form”) of verb 付く tsuku “to stick → to become a certain state or quality”), from the way the husk vaguely resembles bulging red cheeks. The tsuki changes to zuki as an instance of rendaku (連濁).(Can this⁽⁺⁾ etymology be sourced?)

The kanji spellings are examples of jukujikun (熟字訓), with 鬼灯 literally meaning "demon" + "lantern" and the alternate kanji spelling 酸漿 being derived from the Chinese name 酸漿 / 酸浆 (suānjiāng).

• As with many terms that name organisms, this term is often spelled in katakana, especially in biological contexts (where katakana is customary), as ホオズキ (hōzuki).
• The standalone kanji form 鬼灯 appears to be more common than 酸漿, but the latter form may be more common in the kanji spellings of certain compounds.
