From Proto-Italic *deikō.
Pre-Latin [dei̯koː] > Old Latin [de̝ːkoː] > Classical Latin [diːkoː]. In Old Latin, the original diphthong [ei̯] is thought to have coalesced into a long vowel similar to "ē", but with a higher (closer) quality, here transcribed as [e̝ː] (though "ē", "ei" may have actually been [ɛː] and [eː] respectively). This vowel eventually merged with with original [iː], but the spelling "ei" continued to be used, though not consistently, for some time after the merge, and also came to be used unetymologically for original [iː].
deicō (present infinitive deicere, perfect active deixī, supine dictum); third conjugation
