Call out loud to help with the washing (5)
I believe the answer is:
wring
'with the washing' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'call out loud' is the wordplay.
'call' becomes 'ring ' (synonyms).
'out loud' shows a homophone (sound like).
'ring' is a homophone of 'WRING'.
'to help' is the link.
Can you help me to learn more?
(Other definitions for wring that I've seen before include "Extract with difficulty" , "Twist and compress" , "Twist forcibly" , "Extract moisture from" , "Squeeze water out of" .)
