My Flashcards

Definition

Meaning

The national flag of the United Kingdom, combining the crosses of St George (England), St Andrew (Scotland), and St Patrick (Ireland).

A term sometimes used (correctly or incorrectly) to refer to the UK flag when flown as a naval jack (small flag at bow) versus as a national flag; also used in various symbolic contexts representing British identity.

Linguistics

Semantic Notes

Technically, 'Union Jack' is correct when the flag is flown at sea (as a jack); 'Union Flag' is the correct term for the national flag on land, though 'Union Jack' is overwhelmingly common in general usage.

Dialectal Variation

Differences

Frequently Asked Questions

Both are used. 'Union Jack' is traditional and common, especially at sea. 'Union Flag' is technically correct on land, but 'Union Jack' is widely accepted.

They represent the patron saints: St George's cross (England, red on white), St Andrew's cross (Scotland, white diagonal on blue), and St Patrick's cross (Ireland, red diagonal on white).

Yes, but it is considered a distress signal or sign of disrespect. The broader white stripe of the St Andrew's cross should be at the top on the hoist side.
