Say lamb stew is great (7)
I believe the answer is:
abysmal
'great' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'say lamb stew' is the wordplay.
'stew' is an anagram indicator.
'say'+'lamb'='saylamb'
'saylamb' with letters rearranged gives 'ABYSMAL'.
'is' is the link.
Can you help me to learn more?
(Other definitions for abysmal that I've seen before include "Deep, immeasurable" , "Immeasurably bad" , "Dreadful" , "Extreme and deplorable as ignorance may be" , "Extremely bad, appalling" .)
