Samovar, say, freak of nature? (3,3)
I believe the answer is:
tea urn
'samovar' is the definition.
(I've seen this before)
'freak of nature?' is the wordplay.
'freak of' indicates an anagram (I've seen 'freak' mean this (I've seen this in other clues)).
'nature' is an anagram of 'TEA-URN'.
'say' acts as a link.
(Other definitions for tea urn that I've seen before include "Large vessel for brewing" , "item in canteen" , "vessel in mess?" , "Water boiler" , "samovar" .)
