1. Pronunciation and Accent

One of the most significant and distinguishable features of British English is its accent. The Received Pronunciation or RP accent is often portrayed as the "proper" British accent in media and pop culture. However, the RP accent is not representative of the entire country, and regional accents are just as prevalent. From the Scottish lilt to the West Country drawl, accents in the UK vary wildly from region to region. British English also has a unique pronunciation of certain words, including "tomato," "leisure" and "schedule."

2. Spelling and Vocabulary

The spelling of certain words in British English can differ from other versions of the language such as American English. For instance, words such as "colour," "favour" and "labour" use a "u" instead of "color," "favor" and "labor" respectively. The British version of English also has different vocabulary or specific words. For example, "trousers" instead of "pants," "biscuits" instead of "cookies," and "lorry" instead of "truck."

3. Formality

British English tends to be more formal than other versions. It has a greater emphasis on formality, politeness, and etiquette. In spoken and written communication, British English is often more indirect and uses more polite language, especially in formal situations. For example, using "may I ask" instead of "can I ask" or "would you mind if" instead of "could you."

4. Slang and Humour

Another unique feature of British English is its use of slang and humour. British people are known to use slang in their everyday language and popular culture. Common slang phrases include "bloke" for a man, "loo" for a bathroom, and "pub" for a bar or tavern. The use of humour or wit is also a prevalent feature of British English, as seen in British comedy shows such as Monty Python and Blackadder.
