  • US: /ˈfɹʌn.tl̩/, /ˈfɹʌn.l̩/[1]

Etymology

The adjective is partly borrowed from Medieval Latin frontālis (“of the forehead”), recorded in post-classical Latin from the 13th century, and partly formed from English front + -al.[2][3] Most dictionaries take the Latin word as New Latin.[4][5][6][7] It comes from Latin frōns (“forehead, brow, front”), with the suffix -ālis.[2][4][3] An Anglo-Norman adjective fruntel (“front, frontal”) is recorded from the early 13th century.[8]

Earliest recorded meaning

Of or relating to the forehead: 1630, in Edward Poeton's Chyrurgians Closet;[2] Merriam-Webster dates this sense to 1656[4] and Etymonline to the 1650s.[3]

Semantic evolution

The anatomical sense, of the forehead or the bone behind it, came first.[2][5] From it came the brain's frontal lobe (1831) and, as a noun, the frontal bone (1657).[2] The general sense "at or of the front" is recorded from 1777; in the 19th century the word came to be used of a view from the front (1843) and of an attack made directly against an enemy's front (1851), later of any direct challenge or criticism.[2][4] The 20th century added a head-on collision (1945),[2] weather fronts (1908)[2][9] and nudity showing the whole front of the body (1961), as in full frontal.[2][3]

Usage notes

A separate noun frontal, first a band or ornament worn on the forehead and now chiefly a decorated covering for the front of an altar, has a separate source: it is frontel, from Anglo-Norman frontel and Latin frontāle, and is recorded from before 1350; the altar sense dates from 1435.[2][5][10][9]
