Identify America? But this is a European river (5)
I believe the answer is:
tagus
'european river' is the definition.
(I've seen this before)
'identify america?' is the wordplay.
'identify' becomes 'tag' (I've seen this in another clue).
'america?' becomes 'U.S.' (United States).
'tag'+'us'='TAGUS'
'but this is a' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for tagus that I've seen before include "banker" , "Longest river of Iberian peninsular" , "Portugese river" , "Longest river of Iberian peninsula" , "Lisbon's river" .)
