And I wandered in ahead for a takeaway (6)
I believe the answer is:
indian
'a takeaway' is the definition.
I can't tell whether this definition defines the answer.
'and i wandered in ahead' is the wordplay.
'wandered' indicates anagramming the letters.
'ahead' says to put letters next to each other (some letters go in front of others).
'and'+'i'='andi'
'andi' with letters rearranged gives 'dian'.
'dian' after 'in' is 'INDIAN'.
'for' is the link.
Can you help me to learn more?
(Other definitions for indian that I've seen before include "One type of elephant" , "Sub-continental native" , "Type of club, file, tea or summer" , "Eg, native of Delhi" , "American aborigine" .)
