les

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

'name' is the definition.

'french centre of transport' is the wordplay.
'french' becomes 'Old French' (Old French is an example).
'centre' indicates the central letters.
'of transport' becomes 'es' (I can't explain this - if you can you should believe this answer much more).
The middle of 'old' is 'l'.
'l'+'es'='LES'

'the' is the link.

Can you help me to learn more?
