I came over to get tea brewed and dry up (8)
I believe the answer is:
emaciate
'dry up' is the definition.
(thesaurus)
'i came over to get tea brewed' is the wordplay.
'over' says the letters should be written backwards.
'to get' is a charade indicator (letters next to each other).
'brewed' indicates an anagram.
'i'+'came'='icame'
'icame' reversed gives 'emaci'.
'tea' with letters rearranged gives 'ate'.
'emaci'+'ate'='EMACIATE'
'and' is the link.
(Other definitions for emaciate that I've seen before include "Waste away" , "get very thin" , "Make extremely thin" .)
