Made English, upset clan guide is not in union (10)

'made' is the definition.
The answer and definition can be both related to change as well as being past participle verbs.
Perhaps they are linked in a way I don't understand?

'english upset clan guide is not in union' is the wordplay.
I cannot quite understand how this works, but
'english' could be 'e' (abbreviation) and 'e' is located in the answer.
'is' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
