Drop of sherry's more than enough for a little taste (6)
I believe the answer is:
sample
'a little taste' is the definition.
'sample' can be an answer for 'taste' (I've seen this before). I am not certain of the 'a little' bit.
'drop of sherry's more than enough' is the wordplay.
'drop of' suggests taking the first letters.
'more than enough' becomes 'ample' (I've seen this before).
The initial letter of 'sherrys' is 's'.
's'+'ample'='SAMPLE'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for sample that I've seen before include "Specimen; sound clip" , "piece to try" , "Taste; specimen" , "Small representative piece" , "Cross section" .)
