Cannot check around indentation (5)

I believe the answer is:

notch

'indentation' is the definition.
(notch is a kind of indentation)

'cannot check around' is the wordplay.
'around' indicates a hidden word.
'NOTCH' can be found hidden inside 'cannot check'.

(Other definitions for notch that I've seen before include "small score?" , "Dent" , "Indentation - step up" , "Nick - incision" , "Salad plant, garnish" .)

I've seen this clue in The Irish Times.
