In total, everyone gets instructed (3,4)
I believe the answer is:
all told
'in total' is the definition.
(I've seen this before)
'everyone gets instructed' is the wordplay.
'everyone' becomes 'all' (all people).
'gets' means one lot of letters go next to another.
'instructed' becomes 'told' (I've seen this before).
'all'+'told'='ALL TOLD'
(Other definitions for all told that I've seen before include "sum" , "Everyone informed" , "Taking every one into account" , "In summary" , "Taking everything into account" .)
