Etymology

Verb

 * 1)  to encourage, urge

Conjugation
The only attested form of this verb is, appearing once in Ennius: Assuming that this fragmentary verse appears at the end of a line of dactylic hexameter, the vowel in 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 (< ), also attested in Ennius.
