what's the difference between the union flag and the union jack
Union Jack The Union Jack,[note 1][2][3] or Union Flag, is the national flag of the United Kingdom. The flag also has an official or semi-official status in some other Commonwealth realms; for example, it is, by parliamentary resolution, a ceremonial flag in Canada and known there as the Royal Union Flag.[4] Further, it is used as an official flag in some of the smaller British overseas territories. The Union Flag also appears in the canton (upper left-hand quarter) of the flags of several nations and territories that are former British possessions or dominions.
Union Jack When the first flag representing Britain was introduced on the proclamation of King James I in 1606,[19] it became known simply as the "British flag" or the "flag of Britain". The royal proclamation gave no distinctive name to the new flag. The word "jack" was in use before 1600 to describe the maritime bow flag.[9] By 1627 a small Union Jack was commonly flown in this position. One theory goes that for some years it would have been called just the "Jack", or "Jack flag", or the "King's Jack", but by 1674, while formally referred to as "His Majesty's Jack", it was commonly called the "Union Jack", and this was officially acknowledged.[8]
Union Jack The present design of the Union Flag dates from a Royal proclamation following the union of Great Britain and Ireland in 1801.[8] The flag combines aspects of three older national flags: the red cross of St George of the Kingdom of England, the white saltire of St Andrew for Scotland (which two were united in the first Union Flag), and the red saltire of St Patrick to represent Ireland.
Bracket Forms include round (also called "parentheses"), square, curly (also called "braces"), and angle brackets (also called "chevrons"); and various other pairs of symbols.
