Put in a grave position (5)
I believe the answer is:
inter
'position' is the definition.
(I know that inter is a more specific form of the action lay)
'put in a grave' is the wordplay.
I cannot quite understand how this works, but
'in' is within the answer.
The remaining letters 'ter' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for inter that I've seen before include "foreign footballers" , "set underground" , "Prefix meaning between or among" , "Put into the ground" , "Nitre (anag.)" .)
