From Proto-Italic *deikō, from Proto-Indo-European *déyḱeti (“to show, point out”) (reformed as a thematic verb). The perfect forms are derived from Proto-Indo-European *dḗyḱst. For the semantic development compare Proto-Slavic *kazati
Cognates include Oscan 𐌃𐌄𐌝𐌊𐌖𐌌 (deíkum, “to show, point out”), Sanskrit दिशति (diśáti), Ancient Greek δείκνυμι (deíknumi) and 古期英語 tǣċan (English teach).
dīcō (present infinitive dīcere, perfect active dīxī, supine dictum); third conjugation, irregular short imperative
Pre-Classical.
At least one use of the Old Latin "sigmatic future" and "sigmatic aorist" tenses is attested, which are used by Old Latin writers; most notably Plautus and Terence. The sigmatic future is generally ascribed a future or future perfect meaning, while the sigmatic aorist expresses a possible desire ("might want to").
The present passive infinitive in -ier is a rare poetic form which is attested.
Some descendants are from *dire.
According to de Vaan, possibly a back-formation from from compounds in -dicāre, such as iūdicō, iūdicāre (“to judge”). There is evidence of a corresponding first-conjugation verb in Umbrian, provided that 𐌕𐌉𐌊𐌀𐌌𐌍𐌄 (tikamne) derives from Proto-Italic *dik-ā-m(e)n-o-.
