Open

an adjective

Thanks.
Is it sn adjective used as a complement?

Anonymous'The door burst open." What is 'open'?

One view has it that open in this sentence is a subject-oriented secondary predication. Such predications share the qualities of adjectives and adverbs. You may also wish to consider "burst" as a (less usual) linking verb. If you think of open as a complement, it is an adjectival subject compleme

Interesting.
Thanks
