From Proto-Italic *herjō, from Proto-Indo-European *gʰer-. Cognate with Ancient Greek χαίρω (khaírō). The active was lost.
horior (present infinitive horī); third conjugation iō-variant, deponent, no perfect or supine stem
The only attested form of this verb is horitur, appearing once in Ennius:
Assuming that this fragmentary verse appears at the end of a line of dactylic hexameter, the vowel in horitur would be short, making horior a third-conjugation verb. This conjugation is listed in TLL, De Vaan and Lewis and Short.

On the other hand, Gaffiot gives it as a fourth-conjugation verb, perhaps on the basis of the archaic frequentative horitō (< *horitus), also attested in Ennius.
