Initially achieves the legal right to hold property as collateral being a non-native (5)
I believe the answer is:
alien
'a non-native' is the definition.
(I've seen this in another clue)
'initially achieves the legal right' is the wordplay.
'initially' indicates taking the first letters.
'the legal right' becomes 'lien' (I've seen this in another clue).
The first letter of 'achieves' is 'a'.
'a'+'lien'='ALIEN'
'to hold property as collateral being' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for alien that I've seen before include "Otherworldly" , "Unfamiliar; foreign" , "of foreigners" , "Someone from outer space?" , "Little green man, perhaps" .)
