i dont like burnt toast. in this sentence what is burnt particple or verb or adverb or noun ?
"I don't like burnt toast".
"Burnt" is an adjective.
There are several ways of telling that it's an adjective:
(1) Like many adjectives it can be modified by the adverb "very: "I don't like very burnt toast".
(2) It can occur as complement to complex-intransitive verbs: "This toast is burnt".
(3) It can occur as complement to complex-transitive verbs like "find": "I found the toast quite burnt".
"Burnt" has the properties of indisputable adjectives and hence must belong in that class.
