fīō

[ lat. fī + -ō ]

uit. fuiō, v. uig. *bʰuH-

Etymology

From Proto-Italic *fuiō, ultimately from Proto-Indo-European *bʰuH- (“to grow, become, come into being, appear”). Compare with fuī, originally the perfect of this verb but now attached to sum (“I am”); and constructions with -bō, -bam (e.g. amābō, placēbō, nocēbō, monēbam, audiēbam).

The past participle is that of the unrelated verb faciō (“I make, do”). In Latin faciō and fīō were treated as the active and passive equivalents of each other, an example of suppletion.

Pronunciation

• (Classical) IPA^(key): /ˈfiː.oː/, [ˈfiːoː]
• (modern Italianate Ecclesiastical) IPA^(key): /ˈfi.o/, [ˈfiːo]

Note: the i in fi- is pronounced long, except when it is followed by er or en.
