Woman to cover crawler (7)
I believe the answer is:
annelid
'crawler' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'woman to cover' is the wordplay.
'woman' becomes 'Anne' (woman's name).
'to cover' becomes 'lid' (lid is a kind of cover).
'anne'+'lid'='ANNELID'
Can you help me to learn more?
(Other definitions for annelid that I've seen before include "leech, perhaps" , "Class of worms" , "leech, for example" , "Lindane (anag.); a kind of worm" , "Earthworm or leech" .)
