Whence tea may run freely (3)

Ross

I believe the answer is:

urn

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

'whence tea' is the definition.
I can't tell whether this definition defines the answer.

'run freely' is the wordplay.
'freely' is an anagram indicator.
'run' anagrammed gives 'URN'.

'may' acts as a link.

Can you help me to learn more?

(Other definitions for urn that I've seen before include "Samovar, perhaps" , "Vase-shaped vessel" , "Rounded vase" , "Vase for containing ashes" , "Run to get Greek vase" .)

I've seen this clue in the Evening Standard.
