Stop working for American institute in Florida (4)
I believe the answer is:
fail
'stop working' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their base form.
Perhaps they are linked in a way I don't understand?
'american institute in florida' is the wordplay.
'american' becomes 'a' (common abbreviation - e.g. in organisation names).
'institute' becomes 'i' (common abbreviation as in MIT).
'in' indicates putting letters inside.
'florida' becomes 'fl'.
'a'+'i'='ai'
'ai' placed into 'fl' is 'FAIL'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for fail that I've seen before include "collapse" , "Flunk" , "Go wrong" , "Go bankrupt" , "Break down" .)
