No one was in a bad mood, for the day of rejoicing had come.
The holiday is all about rejoicing with family, and is similar to Thanksgiving in vibe.
And so the rejoicing begins among the media and at the White House.
c.1300, "to own, possess, enjoy the possession of, have the fruition of," from Old French rejoiss-, present participle stem of rejoir, resjoir "gladden, rejoice," from re-, which here is of obscure signification, perhaps an intensive (see re-), + joir "be glad," from Latin gaudere "rejoice" (see joy).
Originally sense in to rejoice in. Meaning "to be full of joy" is recorded from late 14c. Middle English also used simple verb joy "to feel gladness; to rejoice" (mid-13c.) and rejoy (early 14c.). Related: Rejoiced; rejoicing.
