Annoying type of grotesque, extreme advertisement on Dart
I believe the answer is:
gadfly
'annoying type' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'grotesque extreme advertisement on dart' is the wordplay.
I cannot really understand how this works, but
'advertisement' could be 'ad' ('ad' can be a synonym of 'advertisement') and 'ad' is found in the answer.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Other definitions for gadfly that I've seen before include "Pestering insect" , "Irritating person; insect" , "Persistently annoying insect" , "troublemaker" , "Bloodsucker; annoying person" .)
