Might such culture or ideas seem strange, strewn around the East? (7)
I believe the answer is:
western
'might such culture or ideas seem' is the definition.
I can't judge whether this definition defines the answer.
'strange strewn around the east?' is the wordplay.
'strange' indicates anagramming the letters.
'around' means one lot of letters goes inside another.
'the east?' becomes 'E' (abbreviation).
'strewn' with letters rearranged gives 'westrn'.
'westrn' going around 'e' is 'WESTERN'.
Can you help me to learn more?
(Other definitions for western that I've seen before include "Cowboys and Indians film" , "American film" , "Old film genre, horse opera" , "Spaghetti film?" , "Cowboys and Indians movie" .)
