what makes a city a city uk

A city in the UK is defined not simply by its size or population but by being granted city status by the British monarch through "Letters Patent," which is a formal royal approval. Historically, having a cathedral was associated with city status, but since the 20th century, the presence of a cathedral is no longer a strict requirement. Towns apply for city status, often during special national events or royal jubilees, and if granted, the place can officially call itself a city. This status is mostly symbolic and confers prestige rather than extra legal powers or administrative rights. For example, some large towns may not be cities because they have not received this royal designation, while some small places with very few residents can be cities if granted city status by the monarch.
