Went out of section of dartboard after treble in the middle (5)
I believe the answer is:
ebbed
'went out' is the definition.
(I've seen this in another clue)
'section of dartboard after treble in the middle' is the wordplay.
'section of dartboard' becomes 'bed' (I am not sure about this - if you are sure you should believe this answer much more).
'after' says to put letters next to each other.
'in the middle' says to take the centre.
The middle letters of 'treble' are 'eb'.
'bed' put after 'eb' is 'EBBED'.
'of' is the link.
Can you help me to learn more?
(Other definitions for ebbed that I've seen before include "Diminished" , "Went out like tide" , "Flowed back or receded" .)
