Is inquisitive mostly about attitude in central American region? (7)
I believe the answer is:
prairie
'central american region?' is the definition.
(as in the middle of the USA)
'is inquisitive mostly about attitude' is the wordplay.
'is inquisitive' becomes 'pries' (to pry is to be inquisitive).
'mostly' means to remove the last letter.
'about' is an insertion indicator.
'attitude' becomes 'air' (I've seen this before).
'pries' with its final letter removed is 'prie'.
'prie' placed around 'air' is 'PRAIRIE'.
'in' is the link.
(Other definitions for prairie that I've seen before include "Open grassland of North America" , "Cowboy song: ` `Bury me not on the lone .......' '" , "-- Dog; -- oyster" , "Open grassland in the USA" , "Schooners once crossed it" .)
