Teenage member from Yarmouth (5)

I believe the answer is:

youth

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

'teenage member from yarmouth' is the definition.
I can't judge whether this definition defines the answer.

'member from yarmouth' is the wordplay.
'member' becomes 'arm' (member can mean a limb).
'from' is a deletion indicator.
'yarmouth' with 'arm' taken out is 'YOUTH'.

Can you help me to learn more?

(Other definitions for youth that I've seen before include "Juvenile" , "Formative years" , "Teenager" , "Lad" , "Immaturity" .)

I've seen this clue in the Evening Standard.
