A short way to encourage caviar producer (8)
I believe the answer is:
sturgeon
'caviar producer' is the definition.
'sturgeon' can be an answer for 'producer' (I have seen 'producer of caviar' mean 'sturgeon' so perhaps 'producer' could also mean 'sturgeon'). I'm not sure about the 'caviar' bit.
'a short way to encourage' is the wordplay.
'a short way' becomes 'st' (abbreviation for street; 'short' suggests a short form).
'to encourage' becomes 'urgeon' (urging on is a kind of encouraging).
'st'+'urgeon'='STURGEON'
Can you help me to learn more?
(Other definitions for sturgeon that I've seen before include "provider of delicacy?" , "Fish yielding caviar and isinglass" , "Our gents caught a large fish" , "Fish producing caviare" , "Something fishy here" .)
