Join where West meets East at Land's End (3)

I believe the answer is:

wed

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

'join' is the definition.
(I know that wed is a type of unify)

'west meets east at land's end' is the wordplay.
'west' becomes 'W' (synonyms).
'meets' means one lot of letters go next to another.
'east' becomes 'e' (synonyms).
'at' means one lot of letters go next to another.
'land's end' becomes 'd' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'w'+'e'+'d'='WED'

'where' acts as a link.

Can you help me to learn more?

(Other definitions for wed that I've seen before include "Unite closely" , "Took in marriage" , "Espouse" , "Take in marriage" , "Married" .)

I've seen this clue in the Evening Standard.
