Measured out by Ted at half time (5)
I believe the answer is:
meted
'measured out' is the definition.
'meted' can be an answer for 'measured' (I've seen this in another clue). I am not certain of the 'out' bit.
'ted at half time' is the wordplay.
'at' means one lot of letters go next to another (I've seen this in other clues).
'half' suggests halving the letters.
'time' with half the letters taken is 'me'.
'ted' put after 'me' is 'METED'.
'by' is the link.
Can you help me to learn more?
(Another definition for meted that I've seen is " Handed out in small portions".)
