Put in type of small English ram (3,2)
I believe the answer is:
set up
'put in' is the definition.
(thesaurus)
'type of small english ram' is the wordplay.
I cannot quite see how this works, but
'small' could be 's' (abbreviation - e.g. clothes size) and 's' is found within the answer.
'english' could be 'e' (abbreviation) and 'e' is located in the answer.
'ram' could be 'tup' (both can mean a male sheep) and 'tup' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for set up that I've seen before include "An arrangement designed to trap or cheat" , "Assemble - design - establish" , "Erect; fix" , "Conspiracy" , "Organise; mount" .)
