Synonym discussion
Sense: adjective/1
All three words describe something that has not reached its final state. 'Incomplete' is the most formal and general — it suggests that some required part is missing, but not necessarily that the work was interrupted at the halfway point (e.g., an incomplete set of data). 'Unfinished' is the everyday word for anything not brought to an end, whether 10 % or 90 % complete (an unfinished letter, an unfinished conversation). 'Half-finished' is more specific: it implies that approximately half the work is done and that this stage is notable, often because work stopped prematurely. A builder might describe a house as 'half-finished' if the walls are up but there are no windows or doors, whereas they'd call it 'unfinished' if only the foundation had been laid. 'Half-done' is an informal equivalent of 'half-finished' and is more common in speech than in formal writing.

Etymology
A compound of 'half' (from Old English 'healf', meaning 'side, part, half') and 'finished' (from Old French 'finiss-', the stem of 'finir' meaning 'to end, complete', ultimately from Latin 'finire'). The compound has been used in English since at least the 18th century to describe things that are only partially completed.
