ˈleap year
[Late ME., f. leap n.1; prob. of much older formation, as the ON. hlaup-ár is presumably, like other terms of the Roman calendar, imitated from Eng.
The name may refer to the fact that in the bissextile year any fixed festival after Feb. falls on the next week-day but one to that on which it fell in the preceding year, not on the next week-day as usual. Cf. med.L. saltus lunæ (OE. mónan hlýp), the omission of a day in the reckoning of the lunar month, made every nineteen years to bring the calendar into accord with the astronomical phenomena.]
A year having one day (now Feb. 29) more than the common year; a bissextile year. † to make leap year of: (fig.) to pass over.
