According to most British dictionaries, British usage agrees with what American dictionaries describe as American English usage, according to which a sweater is either a pullover or a cardigan (which opens at the front). Almost all British dictionaries include cardigans as a type of sweater but at least one includes cardigans as a type of jumper (i.e. most British dictionaries consider "sweater" – and at least one considers "jumper" – to be a hypernym for both pullovers and cardigans).
