Name I made up for a US State (5)
I believe the answer is:
maine
'a us state' is the definition.
(I've seen this before)
'name i made up' is the wordplay.
'made up' is an anagram indicator.
'name'+'i'='namei'
'namei' anagrammed gives 'MAINE'.
'for' acts as a link.
(Other definitions for maine that I've seen before include "North-easterly US state" , "The USA's Pine Tree State" , "N. US Atlantic state" , "Part of America" , "state of USA" .)
