Every teacher has it (4)

I believe the answer is:

each

'every' is the definition.
(synonyms)

'teacher has it' is the wordplay.
'has it' says the answer is hidden in the clue.
'EACH' can be found hidden inside 'teacher'.

(Other definitions for each that I've seen before include "Every - apiece" , "Per person" , "Every single one, person or thing" , "Singly, per capita" , "Ache (anag.)" .)

I've seen this clue in The Mirror and The Daily Express.
