1650s, "pertaining to a feast," from Latin festivus "festive, joyous, gay," from festum "festival, holiday," noun use of neuter of adjective festus "joyful, merry" (see feast (n.)). The word is unattested in English from 1651 to 1735 (it reappears in a poem by William Somervile, with the sense "fond of feasting, jovial"), and the modern use may be a back-formation from festivity. Meaning "mirthful, joyous" in English is attested by 1774. Related: Festively; festiveness.

When the Day crown'd with rural, chaste Delight

Resigns obsequious to the festive Night;

The festive Night awakes th' harmonious Lay,

And in sweet Verse recounts the Triumphs of the Day.

[Somervile, "The Chace"]

c. 1400, "to glisten, be dazzling," probably from Old English *glimsian "shine faintly," part of the group of Germanic words in *gl- having to do with "smooth; shining; joyous," from PIE root *ghel- (2) "to shine." If so, the unetymological -p- would be there to ease pronunciation. From mid-15c. as "to glance with the eyes;" from 1779 as "catch a quick view." Related: Glimpsed; glimpsing.

also merry-making, "a convivial entertainment, a mirthful festival," 1714, from an inversion of the verbal phrase make merry "be happy, be cheerful, be joyous, frolic" (late 14c.); see make (v.) + merry (adj.). The earlier noun was merry-make (1570s). Related: Merry-maker (1827).
