Japanese

Etymology

/fikafika/ → /pikapika/

First attested as ひかひか (fikafika) in the 1595 Dictionarivm Latino Lvsitanicvm, ac Iaponicvm (“Dictionary from Latin into Portuguese, and Japanese”).

Reduplication of the ひか (hika-) root of Old Japanese-derived verb 光る (hikaru, “to shine, to gleam”), which root is from Proto-Japonic *pika. See also *pikaru.

As part of the Late Middle Japanese reintroduction of /p/ as a phoneme, particularly among mimetic words and in some Sino-Japanese compounds, this word regained its original /p/ sound that had by then shifted to /ɸ/.
