Land that came to you in the form of a present? (6)
I believe the answer is:
parcel
'land' is the definition.
(thesaurus)
'came to you in the form of a present?' is the wordplay.
I cannot really see how this works, but
'form' could be 'arc' (arc is a kind of form) and 'arc' is located in the answer.
This may be the basis of the clue (or it may be nonsense).
'that' is the link.
Can you help me to learn more?
(Other definitions for parcel that I've seen before include "Package; piece of land" , "Wrapped missive" , "Packet" , "One wrapped" , "Piece (of land); something to post" .)
