By surface analysis, avus + -unculus. Actually from an n-stem noun suffixed with -culus, from Proto-Indo-European *h₂ewh₂-on-, a dialectal diminutive of *h₂éwh₂ō (“grandfather, adult male relative other than one’s father”) (whence also Proto-Celtic *awontīr (“uncle”) and possibly Proto-Germanic *awô (“grandfather”), from *h₂éwh₂os (“older male relative”)), whence also avus (“grandfather”).
