Performs aerobatics in advertising displays (6)
I believe the answer is:
stunts
This clue might be a double definition.
'performs' is the first definition.
The definition and answer can be both to do with social activities as well as being verbs in their -s form.
Maybe you can see an association between them that I don't see?
'aerobatics in advertising displays' is the second definition.
The definition and answer can be both acts as well as being plural nouns.
Maybe they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for stunts that I've seen before include "Prevents from growing properly" , "Checks growth or development" , "Prevents further development" , "hair-raising exploits" , "Exploits, feats" .)
