From Proto-Italic *sedēō, from earlier *sedējō, from Proto-Indo-European *sed-éh₁-ye-ti (*eh₁-stative), from *sed-, the same root as sīdō (“to settle, sink down”).
Cognates include Sanskrit सीदति (sī́dati), Old Church Slavonic сѣдѣти (sěděti), 古期英語 sittan (English sit).
The perfect sēdī was originally the perfect of the related third-conjugation verb sīdō; this can be seen in how prefixed derivatives of sīdō use sēdī to form their perfects. The same fact is also demonstrated by Umbrian cognates, which feature 𐌔𐌉𐌔𐌕𐌖 (sistu, 3sg. imp.) (from present stem *sizd-) alongside future perfect sesust (from perfect stem *sezd-).
sedeō (present infinitive sedēre, perfect active sēdī, supine sessum); second conjugation, impersonal in the passive
This verb lacks almost all passive forms. Only the third-person singular passive forms are known.
