Say, gallantry medal mounted in holder by soldiers? (6)
I believe the answer is:
eggcup
'holder by soldiers?' is the definition.
(as in the breakfast meal egg and soldiers)
'say gallantry medal mounted' is the wordplay.
'say' becomes 'eg'.
'gallantry medal' becomes 'GC' (short for George Cross).
'mounted' becomes 'up' (I've seen this in other clues).
'eg'+'gc'+'up'='EGGCUP'
'in' acts as a link.
(Other definitions for eggcup that I've seen before include "Bearer of breakfast (with soldiers)" , "Holder of an oval thing" , "Breakfast placed here" , "what held a problem for curate?" .)
