Etymology
The compound noun "half-day" is a transparent formation from two native English elements. "Half" originates from the Proto-Germanic halbaz, conveying the concept of being "partial" or "divided into two," which is a foundational notion in many Indo-European languages. "Day" stems from Proto-Germanic dagaz, related to concepts of burning and the sun, reflecting its original tie to the daylight period. The logical combination of these two morphemes, "partial" + "day," directly yields the modern meaning of a period lasting for only a portion of the standard working or scholastic day. This compounding process exemplifies the straightforward and descriptive nature of English word formation using its Germanic lexical stock.
Analysis

- half: From Old English healf, meaning "side, part," of Germanic origin. Functions as a combining form meaning "partial" or "to the extent of one half."
- day: From Old English dæg, meaning "day, lifetime," of Germanic origin. Functions as the core noun denoting a period of time.
