Russians supplying bags for lettuce? (8)
I believe the answer is:
cossacks
'russians' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'bags for lettuce?' is the wordplay.
'bags' becomes 'sacks' (sack is a kind of bag).
'for' means one lot of letters go next to another (I've seen this in other clues).
'lettuce?' becomes 'cos' (cos is a kind of lettuce).
'sacks' after 'cos' is 'COSSACKS'.
'supplying' acts as a link.
Can you help me to learn more?
(Other definitions for cossacks that I've seen before include "Famous horsemen of S Russia" , "Russian peasants?" , "Members of an elite cavalry corps in tsarist Russia" .)
