American tin (3)

I believe the answer is:

can

I'm a little stuck... Click here to teach me more about this clue!

'tin' is the definition.
(I know that tin can be written as can)

'american' is the wordplay.
'CAN' is hidden in amongst the letters.
However, I am uncertain how this is indicated.

Can you help me to learn more?

(Other definitions for can that I've seen before include "sack from abroad" , "SECOND PART OF 10" , "Possesses ability" , "Vessel" , "Airtight metal container" .)

I've seen this clue in the Evening Standard.
