Rice dish with bit of thyme added on one's knee (7)
I believe the answer is:
patella
'on one's knee' is the definition.
(kneecap)
'rice dish with bit of thyme' is the wordplay.
'rice dish' becomes 'paella' (I've seen this in another clue).
'with' means one lot of letters goes inside another.
'bit of' says to take the initial letters.
The initial letter of 'thyme' is 't'.
'paella' enclosing 't' is 'PATELLA'.
'added' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for patella that I've seen before include "positioned on each knee" , "The formal kneecap" , "Kneecap (anatomy)" , "bit of body usually under trousers!" , "showing a bit of leg" .)
