a dialect is a variety of language used in a particular geographical region. It refers to the particular words chosen, (the word 'bread roll' has a number of different names in different parts of the country such as 'cob', 'bap' and 'bread cake') and also regionally specifically grammatical features (I weren't happy in Yorkshire, we wasn't happy in London)

Some linguists also include accent as a part of dialect.
