calcitrō (present infinitive calcitrāre, perfect active calcitrāvī, supine calcitrātum); first conjugation[1]
Etymology
It is from ⟨*calcitrum⟩ “a kick”, from calx “heel” with the suffix -trum (compare tālitrum), and the verb suffix -ō.[2][1] De Vaan finds the origin of ⟨calx⟩ “heel” unclear; some suggest a non-Indo-European, perhaps Etruscan, source.[3]
Earliest recorded meaning
The OLD's earliest citation is from Cicero, of being refractory.[2] Köbler dates Cicero 81–43 BC.[4]
Semantic evolution
It meant to kick with the heels, of animals, as in Ovid and Pliny the Elder, and figuratively to be refractory, kick against something, as in Cicero.[2][5]
In Ecclesiastical Latin it meant to kick.[6]
