Being also poor is a pity (3,3)
I believe the answer is:
too bad
'is a pity' is the definition.
I can't tell whether this definition defines the answer.
'being also poor' is the wordplay.
'being also' becomes 'too' (I've seen this before).
'poor' becomes 'bad' (similar in meaning).
'too'+'bad'='TOO BAD'
Can you help me to learn more?
(Other definitions for too bad that I've seen before include "What a pity, hard luck" , "A pity, being excessively naughty" , "regrettably" , "That's regrettable, informally" , "Informally regrettable - excessively wicked" .)
