Drawn to suits, soldier in written works promises to pay (9)
I believe the answer is:
litigious
'drawn to suits' is the definition.
I can't judge whether this definition defines the answer.
'soldier in written works promises to pay' is the wordplay.
'soldier' becomes 'GI' (term for US soldier).
'in' is an insertion indicator.
'written works' becomes 'lit' (short for literature).
'promises to pay' becomes 'IOU's' (promises to pay a debt).
'lit'+'ious'='litious'
'gi' going within 'litious' is 'LITIGIOUS'.
Can you help me to learn more?
(Other definitions for litigious that I've seen before include "Disputatious" , "with a fondness for suits" , "Inclined to engage in lawsuits" , "keen to go to court" , "Argumentative" .)
