Act unexpectedly to cut fare for people in US (7)
I believe the answer is:
choctaw
'people in us' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'act unexpectedly to cut fare' is the wordplay.
'unexpectedly' indicates an anagram.
'to cut' is an insertion indicator.
'fare' becomes 'chow' (chow can informally mean food).
'act' anagrammed gives 'cta'.
'cta' put into 'chow' is 'CHOCTAW'.
'for' is the link.
Can you help me to learn more?
(Other definitions for choctaw that I've seen before include "Native American - skating movement - cat chow (anag)" , "figure-skating manoeuvre" , "skating move" , "North American Indian" , "Tribe living in Mississippi, co-watch (anag.)" .)
