Every one in teaching (4)

I believe the answer is:

each

'every one' is the definition.
(I've seen this before)

'in teaching' is the wordplay.
'in' indicates a hidden word.
'EACH' is hidden in the letters of 'teaching'.

(Other definitions for each that I've seen before include "Everyone separately" , "...per head" , "Per capita, apiece" , "Per person" , "This way for a place" .)

I've seen this clue in The Globe and Mail.
