I apologise if this question has already been asked, but I could not find the original post if it has been.
I'd like to know the word which describes the linguistic phenomena whereby a speaker repeats a phrase or word, often at the end of each sentence.
E.g. New Yorkers often say 'right' at the end of almost every sentence, teenage girls in the U.S. often use the word 'literally' at the beginning of sentences, and some British people often use the phrase 'you know' at the end of sentences.
The use of these words and phrases resembles a verbal tick. They are not used for rhetorical or linguistic purposes.
