More about sabulous
The English adjective sabulous is a clear-cut borrowing from Latin sabulōsus ”gravelly, sandy,” a derivative of sabulum “coarse sand, gravel.” Sabulum comes from an assumed Italic psaflom. (Italic is the branch of the Indo-European language family that includes Latin, Oscan, Umbrian, and the modern Romance languages.) Psaflom comes from the same Proto-Indo-European root bhes- “to rub” as Greek psêphos “pebble” and Germanic sandam (Old English and English sand, German Sand). Sabulous entered English in the 17h century.
