Why do UK English speakers omit letters from words when speaking?

Answer 1

English has a time-stressed rhythm. Because of its rhythm, unstressed vowels in particular lose their pure sound and can even be omitted. Another distinctive of British English is that the final "r" is not pronounced, as in "father" or "mother." Since you didn't give any specific examples of words, I'm not sure if I have answered your question. I hope so!

Answer 2

Hello: What an interesting question! Very observant to recognize that UK English speakers drop letters which may make them difficult to understand! In truth, all English speakers from every country drop certain letters when they speak. In fact, all speakers of all languages 'drop letters' when they speak. That is the nature of cultural influence and regional dialect. As an American, I would say the most difficult people here to understand are individuals from New York and New Jersey, as they may have the strongest accent. The people who are the easiest to understand are people from the Mid-west who have a slower way of speaking and more of a 'flat' accent. In my visits to England and Scotland, the easiest people to understand were people from London. The further north I got, especially in Scotland, the thicker the accents became and the more difficult it was to understand what was being said. I was on a tour of the Highlands and stopped in a coffee shop. A couple next to me were speaking Gaelic and it took me a minute to realize it wasn't English!
