Tea and vinegar's out for us: also meat (11)
I believe the answer is:
vegetarians
'us also meat' is the definition.
I can't judge whether this defines the answer.
'tea and vinegar's out' is the wordplay.
'and' is a charade indicator (letters next to each other).
'out' is an anagram indicator (out can mean wrong or inaccurate).
'tea' put after 'vinegars' is 'vinegarstea'.
'vinegarstea' anagrammed gives 'VEGETARIANS'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for vegetarians that I've seen before include "Plant-eaters" , "They don't eat meat" , "No meat eaters" .)
