     When the wedding started I found a spot near Windsor Castle’s entrance, where I could watch the ceremony on a big screen. People who line the roads at weddings are, by definition, the most die-hard royalists, and all the usual figures were out in force: the men bellowing and ringing bells in the hope of convincing a passing American TV crew they are an actual town crier; the men in suits made of Union Jacks.

2. (by extension) The British Empire.

Usage notes

• The Union Jack (also Union Flag, union jack) is regarded as the official flag of the United Kingdom, although technically no law to that effect has ever been passed.
• Some maintain that the name Union Jack is only for when the flag is flown from a jackstaff (sense 3), and that Union Flag is the correct name for sense 1. This is incorrect; both names are equally correct, regardless of where the flag is flown. This misconception possibly stems from the fact that the term jack now specifically refers to a flag flown from a jackstaff (which postdates the use of jack to refer to a flag by at least 150 years). When the flag was named, the term jack could refer to anything that was small, and it was for this reason that it was used to refer to flags flown on ships, but the name Union Jack is not specific to this usage.
