Little bit from Eliot analysed (4)
I believe the answer is:
iota
'little bit' is the definition.
(I've seen this in another clue)
'from eliot analysed' is the wordplay.
'from' indicates the answer is hidden within the clue.
'IOTA' is hidden in the letters of 'eliot analysed'.
(Other definitions for iota that I've seen before include "The Greek i (4)" , "Hint" , "Extremely small amount" , "Ninth Greek character" , "European letter" .)
