Morphology

yesternight = night (semi-transparent) = yester + night

Components 'yester-' (meaning 'previous') + 'night' directly yield 'last night', but 'yester-' is archaic/fossilized and may be unfamiliar to learners.

Etymology

The word yesternight is made of yester- ('the day before') and night, so as a noun it names 'the night before today' or 'last night', though the word is now mainly old-fashioned or literary.
