Morphology

all + day

The meaning 'for the entire duration of the day' is directly and compositionally derived from combining 'all' (the whole) with 'day' (a period of daytime/24 hours); this quantifier + time-noun pattern is transparent and cross-linguistically common. A B1 learner who knows both constituent words can reliably infer the MWE meaning without prior exposure.

Etymology

All day comes from the simple image of doing something for all of the day, from morning until night. So if you say you did something all day, you mean 'continuously' or 'for the entire day'.
