Everyone has a wish from the beginning (3,5)
I believe the answer is:
all along
'from the beginning' is the definition.
(I've seen this before)
'everyone has a wish' is the wordplay.
'everyone' becomes 'all' (all people).
'has' is a charade indicator (letters next to each other).
'wish' becomes 'long' (I've seen this in other clues).
'all'+'a'+'long'='ALL ALONG'
(Other definitions for all along that I've seen before include "From the outset" , "Consistently over a period of time" , "What across answers have always been" , "From the beginning" , "Covering the entire distance" .)
