With no time at the end, competition is deadlocked (4)
I believe the answer is:
even
'deadlocked' is the definition.
(I've seen this in another clue)
'with no time at the end competition' is the wordplay.
'with' is a charade indicator (letters next to each other).
'no time' becomes 'eve' (I am not sure about this - if you are sure you should believe this answer much more).
'at the end' suggests the final letters.
The last letter of 'competition' is 'n'.
'eve' put next to 'n' is 'EVEN'.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for even that I've seen before include "like six or twelve" , "When darkness starts to fall" , "Pantomime" , "Regular; calm" , "Level as odds may be" .)
