Ditch some merriment (2,2)
I believe the answer is:
ha ha
This clue might be a double definition.
'ditch' is the first definition.
(I know that ha-ha is a type of ditch)
'some merriment' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
Can you help me to learn more?
(Other definitions for ha ha that I've seen before include "feature of many a country estate" , "A wall" , "Ditch" , "Bound" , "thing to keep animals out!" .)
