Ditch husband with expression of pleasure (2,2)
I believe the answer is:
ha ha
'ditch' is the definition.
(I know that ha-ha is a type of ditch)
'husband with expression of pleasure' is the wordplay.
I cannot quite understand how this works, but
'husband' could be 'h' and 'h' is located in the answer.
'expression' could be 'aha' (I have seen 'Expression of surprise ' mean 'aha' so perhaps 'expression' could also mean 'aha') and 'aha' is found in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for ha ha that I've seen before include "laughter" , "Ditch" , "laugh" , "Bound" , "A wall" .)
