First we said, that an adverb describes the quality of the verb. Example:

nom bo'Degh vISop
quickly I eat the bird

Then we said that an adverb can refer to the verb of a {-bogh} clause too. Example:

nom bo'Degh'e' HoHta'bogh SoSwI' vISop
quickly I eat the bird which was killed by my mother
or
I eat the bird which my mother quickly killed

but now I need to ask..

Can an adverb refer to a be-verb which is acting as an adjective ? Example:

tlhoy bo'Degh tIn vISop
I eat the excessively big bird
