PIE roots

A suppletive paradigm consisting of two different roots.

The present stem is from Proto-Italic *ferō, from Proto-Indo-European *bʰéreti ‎(to bear, carry), from the root *bʰer-. Cognates include Sanskrit भरति ‎(bhárati), Ancient Greek φέρω ‎(phérō), Old English beran (English bear).

The perfect stem, originally of tollō, is from Proto-Italic *tetolai, from Proto-Indo-European *tetólh₂e ‎(to be holding up), from the root *telh₂-. The stem of lātus has the same root, reduced from Proto-Italic *tlātos, from Proto-Indo-European *tl̥h₂tós. It is cognate with English thole ‎(to endure).



ferō ‎(present infinitive ferre, perfect active tulī or tetulī, supine lātum); third conjugation, irregular
