Almost get to every one (4)
I believe the answer is:
each
'every one' is the definition.
(I've seen this in another clue)
'almost get' is the wordplay.
'almost' means to remove the first letter.
'get' becomes 'reach' (reaching is a kind of getting).
'reach' with its initial letter removed is 'EACH'.
'to' is the link.
(Other definitions for each that I've seen before include "every one of a group" , "every individual" , "Every single one, person or thing" , "Every - apiece" , "Every one of a number" .)
