Inclination to drill until Thursday (4)

I believe the answer is:

tilt

'inclination' is the definition.
(I know that inclination can be written as tilt)

'to drill until thursday' is the wordplay.
'to drill' indicates a hidden word (the answer drills into the clue).
'TILT' is hidden in the letters of 'until thursday'.

(Other definitions for tilt that I've seen before include "Lean to one side" , "Inclination, joust" , "Heel over" , "Be inclined" , "Lean sideways" .)

I've seen this clue in The Independent.
