A cavalryman cutter? (6)
I believe the answer is:
lancer
'a cavalryman' is the definition.
(I know that lancer is a type of cavalryman)
'cutter?' is the wordplay.
I cannot really see how this works, but
'cutter?' could be 'lance' (lance is a kind of cutter) and 'lance' is present in the answer.
A single letter 'r' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for lancer that I've seen before include "Spearman (as in dance?)" , "Former cavalryman" , "Cavalry soldier" .)
