avunculus

Latin

Etymology

By surface analysis, avus +‎ -unculus. Actually from an n-stem noun suffixed with -culus, from Proto-Indo-European *h₂ewh₂-on-, whence also Proto-Celtic *awontīr (“uncle”) and possibly Proto-Germanic *awô (“grandfather”), from *h₂éwh₂os (“older male relative”), whence also avus (“grandfather”).
