Seabat flies and recedes (6)
I believe the answer is:
abates
'recedes' is the definition.
Although both the answer and definition are verbs in their -s form, I cannot see how they can define each other.
'seabat flies' is the wordplay.
'flies' is an anagram indicator.
'seabat' anagrammed gives 'ABATES'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for abates that I've seen before include "'Lets up, dies away (6)'" , "moderates" , "Becomes less intense" , "Subsides" , "Goes down like storm" .)
