One can get maty out of friendship (5)
I believe the answer is:
amity
'friendship' is the definition.
(I've seen this in other clues)
'one can get maty' is the wordplay.
I cannot really see how this works, but
'one' could be 'i' (Roman numeral) and 'i' is present in the answer.
an anagram of 'maty' is 'amty' which is within the left over letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'out of' acts as a link.
Can you help me to learn more?
(Other definitions for amity that I've seen before include "Friendliness" , "Friendly relations" , "warmth" , "Friendly feeling, fraternity" , "Cordiality" .)
