One hunting wine aisle, initially blended port bottles (8)
I believe the answer is:
predator
'one hunting' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
'wine aisle initially blended port bottles' is the wordplay.
'wine' becomes 'red' (red is a type of wine).
'initially' suggests taking the first letters.
'blended' is an anagram indicator.
'bottles' indicates putting letters inside (bottle can mean to contain).
The initial letter of 'aisle' is 'a'.
'port' is an anagram of 'ptor'.
'red'+'a'='reda'
'reda' going into 'ptor' is 'PREDATOR'.
Can you help me to learn more?
(Other definitions for predator that I've seen before include "Film" , "eagle, say" , "One on the hunt" , "Ruthless type" , "Exploitative person" .)
