Lacking refinement in lament that ignores Unknown Soldier? (9)
I believe the answer is:
inelegant
'lacking refinement' is the definition.
(I've seen this before)
'in lament that ignores unknown soldier?' is the wordplay.
'lament' becomes 'elegy' (synonyms).
'that ignores' is a deletion indicator.
'unknown' becomes 'y' (algebra).
'soldier?' becomes 'ant' (soldier is a type of ant).
'elegy' with 'y' taken out is 'eleg'.
'in'+'eleg'+'ant'='INELEGANT'
(Other definitions for inelegant that I've seen before include "Eglantine (anag)" , "Ugly" , "Unpolished" , "Not stylish or refined" , "ungainly" .)
