mid-13c., "timid, fearful, full of terror," from fright (n.) + -ful. The prevailing modern sense of "alarming, full of occasion for fright" is from c. 1600.

Related: Superlatively; superlativeness.
The noun is attested from 1520s, originally in the grammatical sense, "a word in the superlative;" hence "exaggerated language" (1590s).
