Uneven — rum (3)
I believe the answer is:
odd
I believe this is a double definition.
'uneven' is the first definition.
(I've seen this before)
'rum' is the second definition.
(rum can mean strange or dubious)
(Other definitions for odd that I've seen before include "Not matching" , "Peculiar or eccentric" , "like half the numbers?" , "Matchless" , "Weird" .)
