Show affection after low introduction to school (6)
I believe the answer is:
smooch
'show affection' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'low introduction to school' is the wordplay.
'low' becomes 'moo' (both can mean to make the noise of a cow).
'introduction to' is an insertion indicator (inserted letters are introduced into the word).
'school' becomes 'sch' (abbreviation).
'moo' inserted inside 'sch' is 'SMOOCH'.
'after' is the link.
Can you help me to learn more?
(Other definitions for smooch that I've seen before include "neck" , "Dance slowly while in an embrace - kiss - pet" , "Kiss and caress slangily" , "Kiss and cuddle (colloq.)" , "Canoodle" .)
