Weary time with one communist (5)
I believe the answer is:
tired
'weary' is the definition.
(similar in meaning)
'time with one communist' is the wordplay.
'time' becomes 't' (abbreviation).
'with' is a charade indicator (letters next to each other).
'one' becomes 'i' (Roman numeral).
'communist' becomes 'red' (red can informally mean communist).
't'+'i'+'red'='TIRED'
(Other definitions for tired that I've seen before include "Weary or fed up" , "Depleted of energy" , "Exhausted" , "In need of rest" , "Played out" .)
