dico
Etymology and origin of the Latin word dico
Pronunciation
Forms
dīcō (present infinitive dīcere, perfect active dīxī, supine dictum); third conjugation, irregular short imperative[1]
Etymology
It is inherited from Proto-Italic *deik-e/o- (“to say”), inherited from Proto-Indo-European *déyḱeti (“to show, point out”).[2][1] The meaning shifted from “to show” to “to say”, and the old spelling deico appears in early inscriptions such as the decree on the Bacchanalia.[2][3][1] The perfect dīxī continues a Proto-Indo-European s-aorist.[2][1]
Cognate with Oscan deíkum (“to say”), Umbrian teitu (“let him say”), Sanskrit दिशति (diśáti, “points out”), Ancient Greek δείκνυμι (deíknumi, “to show”) and Old English tǣċan (“to show, teach”).[2][3][1] The root noun *-dik- “saying” is seen in iūdex and vindex, and Oscan meddíss (“magistrate”) is a parallel formation.[2]
Earliest recorded meaning
De Vaan dates it from Naevius onwards.[2] In Plautus it means to speak or talk, as of someone who “speaks harshly to a free man”.[3]
Semantic evolution
The verb covered speaking in general and making a speech in court or assembly, and Cato defined the orator as vir bonus dicendi peritus.[3] It meant to say or state something, with indirect statement, question or command, and in law to allege or assert positively.[3] It also meant to use a word or term, to pronounce, to mention, to celebrate in poetry, and to mean or refer to.[3][4]
With a predicate it meant to call or name someone, and in public life to appoint, as in dictator dictus est.[3] It was used of fixing a day or terms and of naming a dowry.[3] It survives as French dire, Italian dire and Romanian zice,[1] and its participle dictum gave English dictum and, through Italian, English ditto.[5]
