Morphology

union + jack

The compound is directly compositional: 'union' (a joining/union of entities) combined with 'jack' (a small flag) yields a flag representing a union. Although 'Union Jack' is a conventional proper name for the UK flag, its basic meaning as the flag of a union is predictable from the constituents, so a learner who knows both words would recognize it refers to a flag of a union (in this case the UK).

Etymology

The name Union Jack comes from joining three old crosses: the red cross of St George for England, the diagonal white cross of St Andrew for Scotland, and the diagonal red cross of St Patrick for Ireland. At first the word 'jack' meant a small flag flown on ships, so the joined flag was called the Union Jack, and that's why the name now means the national flag of the United Kingdom.
