Woman finally delighting in breakfast food, like the governor (9)
I believe the answer is:
viceregal
'the governor' is the definition.
(I've seen this before)
'woman finally delighting in breakfast food' is the wordplay.
'woman' becomes 'Vi' (short for Violet).
'finally' indicates one should take the final letters.
'in' indicates putting letters inside.
'breakfast food' becomes 'cereal' (cereal is a kind of breakfast food).
The last letter of 'delighting' is 'g'.
'g' placed inside 'cereal' is 'ceregal'.
'vi'+'ceregal'='VICEREGAL'
'like' is the link.
(Other definitions for viceregal that I've seen before include "Relating to a colonial governor representing a monarch" , "Relating to a colonial ruler" .)
