Just out on the outskirts of New York forest (6)
I believe the answer is:
newest
'just out' is the definition.
(I've seen this in another clue)
'on the outskirts of new york forest' is the wordplay.
'on' is a charade indicator (letters next to each other).
'the outskirts of' says to hollow out the word (remove centre letters) (only letters on the outskirts).
'new' becomes 'neverseenbefore' (I've seen this in another clue).
'york forest' becomes 'west' (I am not sure about this - if you are sure you should believe this answer much more).
'neverseenbefore' with its centre removed is 'ne'.
'ne'+'west' is 'NEWEST'.
Can you help me to learn more?
(Other definitions for newest that I've seen before include "Most pristine or latest" , "Freshest, most modern" , "most recently released?" , "Latest novel" , "Superlatively modern" .)
