to have a fever, fever to be sick with a fever Though in a number of languages one can say ‘a person has a fever,’ in some languages the reverse expression is used, for example, ‘the fever has a person.’ Similarly, instead of saying ‘a person has a disease,’ it is ‘the disease which grabs a person.’ One may often speak of a fever as ‘to become hot’ or ‘to burn’ or ‘to be sick with burning.’
