Monotony coming from Edward, first person in corporation (6)
I believe the answer is:
tedium
'monotony' is the definition.
(thesaurus)
'edward first person in corporation' is the wordplay.
'edward' becomes 'ed'.
'first person' becomes 'i'.
'in' indicates putting letters inside.
'corporation' becomes 'tum' (I've seen this before).
'ed'+'i'='edi'
'edi' put within 'tum' is 'TEDIUM'.
'coming from' is the link.
(Other definitions for tedium that I've seen before include "boring" , "State of being bored" , "Boredom, tiresomeness" , "Boredom, mental weariness" , "Banality" .)
