Odd copper in front of us touring port (7)
I believe the answer is:
curious
'odd' is the definition.
(thesaurus)
'copper in front of us touring port' is the wordplay.
'copper' becomes 'cu' (chemical symbol).
'in front of' says to put letters next to each other.
'touring' means one lot of letters goes inside another (touring can mean going round).
'port' becomes 'rio' (I've seen this before).
'cu'+'us'='cuus'
'cuus' enclosing 'rio' is 'CURIOUS'.
(Other definitions for curious that I've seen before include "Odd or eager to know" , "Eager to learn something" , "Odd, peculiar" , "Strange - inquisitive" , "Intrigued" .)
