adverb or adjective

[hector51]

hi teachers!
please check this sentence for me:
The singer appeared unannounced at the start of the encore to sing a cover of The Beatles' The Long and Winding Road, accompanied by Prince on guitar.

(an article form BBC.com BBC NEWS | Entertainment | Sir Elton joins Prince in London)

I think the word in bold should be an adjective.....why did they use an adverb?is that sentence gramatically correct?

thanks!

The word in bold is not an adverb, but a past participle adjective.

It's an adverb because it is is describing the way in which the singer appeared, not the singer himself. The word could alsio be used as an adjective if we were taliking about an 'unannounced concert'.

Yes, you are right. I thought the verb "appear" is a linking verb, but it is not in this context, as in, for example, he appears unwilling to concede.

He was willing: Complement (or predicate adjective) of linking verb was.
He appeared willing: Complement (or predicate adjective) of linking verb appeared.
He became willing: Complement (or predicate adjective) of linking verb became.

He entered the room unannounced: adverb.
He entered the room willingly: adverb.

The picture above is of Xiao Li: adverb = The picture (that is) above.....
The clouds above: adverb.

Something's wrong. A perfect participle can be an adjective but not an adverb.

Yes, I believe you are right (although I have never heard the term "perfect participle"). My take on this is that the "unannounced" is actually a reduced relative clause; try putting "announced" in commas (as in a non-restrictive relative clause) and it seems clearer.
The singer appeared, [who was] unannounced, at the start of the encore to sing a cover of The Beatles' The Long and Winding Road, accompanied by Prince on guitar.

"Unannounced" is a passive construction that has been reduced and often we don't punctuate a single adjective post-reduction if it follows the noun (although we often do if it is at the beginning of the sentence; e.g. Unannounced, the singer....)
