Troop leaders scorn teachers (12)

I believe the answer is:

scoutmasters

I'm a little stuck... Click here to teach me more about this clue!

'scorn teachers' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps they are linked in a way I don't understand?

'troop leaders' is the wordplay.
'troop' becomes 'scout troop' (synonyms).
'leaders' becomes 'masters' (master is a kind of leader).
'scout'+'masters'='SCOUTMASTERS'

Can you help me to learn more?
