Posers like drinking spirit with a twist (7)
I believe the answer is:
enigmas
'posers' is the definition.
(I've seen this in another clue)
'like drinking spirit with a twist' is the wordplay.
'like' becomes 'sme' (I can't justify this - if you can you should believe this answer much more).
'drinking' means one lot of letters goes inside another (inserted letters are consumed or drunk).
'spirit' becomes 'gin' (alcoholic spirit).
'with' means one lot of letters goes inside another.
'twist' shows that the letters should be reversed in order (I've seen 'twisted ' mean this).
'sme' going around 'gin' is 'smgine'.
'smgine' enclosing 'a' is 'samgine'.
'samgine' backwards is 'ENIGMAS'.
Can you help me to learn more?
