Twist lid of tea container (4)
I believe the answer is:
turn
'twist' is the definition.
(synonyms)
'lid of tea container' is the wordplay.
'lid of' says to take the initial letters (in a down clue, the lid could be the top letter).
'container' becomes 'urn' (urn is a kind of container).
The first letter of 'tea' is 't'.
't'+'urn'='TURN'
(Other definitions for turn that I've seen before include "Go - short walk" , "Change one's mind" , "Bend, move round" , "Go; spin (cricket)" , "Go off - performance" .)
