America's capital? American can identify Texas capital (6)
I believe the answer is:
austin
'texas capital' is the definition.
(I've seen this in another clue)
'america's capital? american can' is the wordplay.
'capital?' indicates taking the first letters (I've seen 'capital' mean this).
'american' becomes 'us' (abbreviation for United States).
'can' becomes 'tin' (both are metal containers).
The first letter of 'americas' is 'a'.
'a'+'us'+'tin'='AUSTIN'
'identify' is the link.
(Other definitions for austin that I've seen before include "State capital of Texas" , "The capital of Texas (6)" , "Texan state capital" , "Capital city of Texas" , "Engineer" .)
