Article by Signora Peron, born in Chile, within reach (10)
I believe the answer is:
achievable
'within reach' is the definition.
(I've seen this in another clue)
'article by signora peron born in chile' is the wordplay.
'article' becomes 'a' (the indefinite article in English).
'by' means one lot of letters go next to another.
'signora peron' becomes 'Eva' (Eva Peron, former First Lady of Argentina).
'born' becomes 'b' (abbreviation next to the year of someone's birth).
'in' indicates putting letters inside.
'eva'+'b'='evab'
'evab' going within 'chile' is 'chievable'.
'a'+'chievable'='ACHIEVABLE'
(Other definitions for achievable that I've seen before include "Doable, winnable" , "can be reached" , "Able to be accomplished" .)
