Where Americans get cross, put in a bad seat (5)
I believe the answer is:
texas
'where americans' is the definition.
The answer is a location as well as being a singular noun. This is suggested by the definition.
'cross put in a bad seat' is the wordplay.
'cross' becomes 'x' (X is cross-shaped).
'put in' indicates putting letters inside.
'a bad' is an anagram indicator.
'seat' anagrammed gives 'teas'.
'x' inserted within 'teas' is 'TEXAS'.
'get' is the link.
Can you help me to learn more?
(Other definitions for texas that I've seen before include "Large US state" , "Second-largest US state by area" , "America's Lone Star State" , "American state, capital Austin" , "Breed of cattle -- non-Goths relax (anag)" .)
