Morphology

leap + year

The element 'leap' evokes a change or addition and 'year' is transparent, so learners can infer this refers to a special kind of year; however the precise meaning — that it has an extra day every four years — is a specific calendrical fact not directly predictable from the constituents alone. Because understanding the exact nature and frequency of the addition requires cultural/lexical knowledge beyond literal composition, the expression is only partly transparent to a B1 learner.

Etymology

Leap year may come from one popular story: because an extra day, February 29, is added, calendar dates after February 28 seem to leap forward and jump over a day of the week. That's why the phrase means a year with an 'extra day'.
