A pair of Charlies pinching a half-French fellow? (8)
I believe the answer is:
academic
'french fellow?' is the definition.
'academic' can be an answer for 'fellow?' (I've seen this before). I'm not sure about the 'french' bit.
'a pair of charlies pinching a half' is the wordplay.
'a pair of' says to double the letters (I've seen 'pair' mean this).
'charlies' becomes 'ac' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'pinching' means one lot of letters goes inside another (taking inside).
'a half' becomes 'demi' (prefix as in 'demigod').
'ac' doubled is 'acac'.
'acac' going around 'demi' is 'ACADEMIC'.
Can you help me to learn more?
(Other definitions for academic that I've seen before include "Associated with places of higher learning" , "A person studying" , "Scholarly; irrelevant" , "University lecturer" , "This person may be a professor" .)
