Leaves all bundled up, prepared for a dousing (3,3)
I believe the answer is:
tea bag
'a dousing' is the definition.
Although both the answer and definition are singular nouns, I can't see how one could define the other.
'leaves all bundled up prepared' is the wordplay.
I cannot quite see how this works, but
'leaves' could be 'tea' (as in tea leaves) and 'tea' is found within the answer.
The remaining letters 'bag' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'for' is the link.
Can you help me to learn more?
(Other definitions for tea bag that I've seen before include "Container for leaves" , "container full of holes" , "Beverage in an individual serving" , "Sachet to put in pot" , "One for the pot" .)
