Grasping an indefinite number of meat sandwiches (5)
I believe the answer is:
venal
'grasping' is the definition.
(thesaurus)
'indefinite number of meat sandwiches' is the wordplay.
'indefinite number of' becomes 'n' (I can't explain this - if you can you should believe this answer much more).
'meat' becomes 'veal' (veal is a kind of meat).
'sandwiches' indicates putting letters inside (inserted letters are sandwiched in).
'n' going within 'veal' is 'VENAL'.
'an' is the link.
Can you help me to learn more?
(Other definitions for venal that I've seen before include "can be bought cheaply" , "Corruptible" , "Capable of being corrupted" , "Susceptible to bribery" , "Influenced by bribery, corrupt" .)
