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 there's a link between them I don't understand?
'like sheep meat or dog but not llama' is the wordplay.
I cannot quite see 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 present in the answer.
No letters remain.
This explanation may well be incorrect...
'at' is the link.
Can you help me to learn more?
(Another definition for muttony that I've seen is " such a meaty bone?".)
