She appears to be tired.
If we write the above sentence as 'She appears tired'....the word 'tired' is an adjective working as Subjective complement.
My question is if we write 'she appears to be tired' then
'to be tired' here is an infinitive phrase working as adjective and a subjective complement?
And I don't know how to put it but I still gonna try in 'to be tired', 'to be' is an infinitive but here,inside the phrase, how this infinitive is working as an adjective, noun or an adverb (Like is it modifying the word tired or what)?
Please answer or even if u don't know the answer please share ur view....I have been stucked in these questions for a long time.
