Wearying Ros and Mike getting together distractedly (7)
I believe the answer is:
irksome
'wearying' is the definition.
(thesaurus)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for irksome that I've seen before include "Annoying - tedious" , "Tediously annoying" , "Bothersome, annoying" , "Tiresome, irritating" , "'Tedious, tiresome (7)'" .)
