Like sheep meat or dog but not llama, at first (7)
I believe the answer is:
muttony
'first' is the definition.
Both the definition and answer are adjectives.
Maybe they are linked in a way I don't understand?
'like sheep meat or dog but not llama' is the wordplay.
I cannot really understand how this works, but
'like' could be 'y' (similar in meaning) and 'y' is found within the answer.
'sheep' could be 'mutton' (I've seen this before) and 'mutton' is located in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'at' acts as a link.
Can you help me to learn more?
(Another definition for muttony that I've seen is " such a meaty bone?".)
