Jollify comes from the word jolly, “in good spirits; lively; merry,” which entered English in 1275–1325.
Jolly comes from the Middle English word joli, probably originally from the Old Norse word jōl, from which we get Yule.
Yule entered English before 900 and means “Christmas day” or “Christmastide” (a word for the period from Christmas Eve to related feast days in early January).

Also related, perspicuous, “clearly expressed or presented,” came from the Latin word perspicuus, which means “transparent, clearly visible,” and entered English around 1570-80.
