Yank’s never accepting notice, presently (8)
I believe the answer is:
nowadays
'presently' is the definition.
(synonyms)
'yank's never accepting notice' is the wordplay.
'yank's never' becomes 'noways' (I can't justify this - if you can you should believe this answer much more).
'accepting' is an insertion indicator (inserted letters are accepted).
'notice' becomes 'ad' (short for advert).
'noways' placed around 'ad' is 'NOWADAYS'.
Can you help me to learn more?
(Other definitions for nowadays that I've seen before include "In the 21st century" , "Currently" , "in the current period?" , "present times" , "At this juncture" .)
