Just a taste is more than plenty (6)
I believe the answer is:
sample
'just a taste' is the definition.
(I've seen this in another clue)
'more than plenty' is the wordplay.
'more than' becomes 's' (I can't justify this - if you can you should believe this answer much more).
'plenty' becomes 'ample' (ample means enough or plenty).
's'+'ample'='SAMPLE'
'is' is the link.
Can you help me to learn more?
(Other definitions for sample that I've seen before include "Specimen; sound clip" , "Cross section" , "Small part intended to represent the whole" , "Taste; specimen" , "Specimen, try out" .)
