Mon Oncle 's lead gets Broadway award for routine (8)
I believe the answer is:
monotony
'mon oncle 's lead' is the definition.
I can't tell whether this defines the answer.
'broadway award for routine' is the wordplay.
'broadway award' becomes 'tony' (I've seen this in another clue).
'for' says to put letters next to each other (I've seen this in other clues).
'routine' becomes 'mono' (I can't explain this - if you can you should believe this answer much more).
'tony' put after 'mono' is 'MONOTONY'.
'gets' acts as a link.
Can you help me to learn more?
(Other definitions for monotony that I've seen before include "fixed routine" , "Tedious lack of variety" , "Sameness" , "Tediousness" , "boring routine" .)
