Terribly sallow, one admits (6)

I believe the answer is:

allows

'one admits' is the definition.
(I've seen this in another clue)

'terribly sallow' is the wordplay.
'terribly' is an anagram indicator.
'sallow' with letters rearranged gives 'ALLOWS'.

(Other definitions for allows that I've seen before include "Grants leave" , "Gives permission" , "Permits to do something" , "Tolerates" , "Permits or agrees" .)

I've seen this clue in the Evening Standard.
