Abducted while the child slept (9)
I believe the answer is:
kidnapped
'abducted while' is the definition.
'kidnapped' can be an answer for 'abducted' (I've seen this before). I'm not sure about the 'while' bit.
'child slept' is the wordplay.
'child' becomes 'kid' (synonyms).
'slept' becomes 'napped' (napping is a kind of sleeping).
'kid'+'napped'='KIDNAPPED'
'the' acts as a link.
Can you help me to learn more?
(Other definitions for kidnapped that I've seen before include "Classic novel" , "Book by Stevenson" , "Abducted" , "Taken prisoner for ransom - R. L. Stevenson novel" , "novel for a boy" .)
