Even English game bird passes over India (5)
I believe the answer is:
equal
'even' is the definition.
(similar in meaning)
'english game bird passes over india' is the wordplay.
'english' becomes 'e' (abbreviation).
'game bird' becomes 'quail' (quail is a kind of game bird).
'passes over' is a deletion indicator (pass over can mean to ignore).
'india' becomes 'i' (phonetic alphabet: alpha, bravo, charlie etc.).
'quail' with 'i' taken away is 'qual'.
'e'+'qual'='EQUAL'
(Other definitions for equal that I've seen before include "The same in all aspects" , "Be as good as, match" , "The same in quantity, status etc" , "more or less" , "The same in size, amount or value, etc." .)
