To want that is right though comparatively broke? (7)
I believe the answer is:
needier
'comparatively broke?' is the definition.
Both the answer and definition are comparative adjectives. Perhaps you can see an association between them that I don't see?
'to want that is right' is the wordplay.
'to want' becomes 'need' (needing is a kind of wanting).
'that is' becomes 'ie' (short for Latin 'id est', 'that is').
'right' becomes 'r' (common abbreviation).
'need'+'ie'+'r'='NEEDIER'
'though' is the link.
Can you help me to learn more?
(Other definitions for needier that I've seen before include "more impoverished" , "Poorer" , "In more want" , "Those with fewer resources are" , "More disadvantaged" .)
