Dish of stew or stick with black olive starter? (5)
I believe the answer is:
gumbo
'dish of stew' is the definition.
(gumbo is a type of stew)
'stick with black olive starter?' is the wordplay.
'stick' becomes 'gum' (gum can mean to glue or stick).
'with' means one lot of letters go next to another.
'starter?' says to take the initial letters (I've seen 'starters' mean this).
The initial letters of 'black olive' is 'bo'.
'gum'+'bo'='GUMBO'
'or' is the link.
(Other definitions for gumbo that I've seen before include "Cajun chicken dish" , "Thick soup" , "Patois" , "Soup from Louisiana" , "Okra pods" .)
