Vessel from which to possibly eat some potatoes (6)
I believe the answer is:
teapot
'vessel' is the definition.
(teapot is a kind of vessel)
'which to possibly eat some potatoes' is the wordplay.
'which' becomes 'tea' (I am not sure about this - if you are sure you should believe this answer much more).
'possibly' indicates an anagram.
'eat' means one lot of letters goes inside another.
'some' indicates taking the first letters.
The initial letter of 'potatoes' is 'p'.
'to' with letters rearranged gives 'ot'.
'tea'+'ot'='teaot'
'teaot' enclosing 'p' is 'TEAPOT'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for teapot that I've seen before include "Vessel for brewing leaves" , "Home brewing is done here!" , "Container for a brew" , "Peat to brew leaves in" , "where one might find leaves" .)
