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

'shropshire town' is the definition.
I know nothing about this answer so I can't judge whether this works.

'welsh earl heading to major' is the wordplay.
'welsh' becomes 'W' (abbreviation).
'earl' becomes 'e'.
'heading to' indicates taking the first letters (the head of the word).
The initial letter of 'major' is 'm'.
'w'+'e'+'m'='WEM'

Can you help me to learn more?

(Other definitions for wem that I've seen before include "Protuberant part" , "Corporation" .)
