Lousy letters from Lamb, say (7)
I believe the answer is:
abysmal
'lousy letters from lamb say' is the definition.
I can't judge whether this defines the answer.
'from lamb say' is the wordplay.
'from' indicates anagramming the letters (from the letters).
'lamb'+'say'='lambsay'
'lambsay' is an anagram of 'ABYSMAL'.
Can you help me to learn more?
(Other definitions for abysmal that I've seen before include "Pathetic" , "Deep, immeasurable" , "Immeasurably bad" , "Bottomless - profound" , "Very bad or limitless" .)
