Burned and burnt are usually used in the exact same way. In British, Irish, and Australian English, they are the same word, but in American English, there is a difference between the two words.
Usually, the words burned and burnt refer to one of two things: the first is when someone has committed an act of burning in the past, and the second is when an object has undergone burning in the past. This means the words are used either as adjectives or verbs.
In American English, however, the word “burned” is a verb. This means that it refers to an act of burning committed in the past.
The word “burnt” is an adjective in American English. This means that it refers to the quality an object has when it has undergone burning in the past.
|Refers to the act of burning having already been done.||Refers to the object that has already undergone burning.|
While they both refer to objects being lit on fire, their usage is different in American English because they are different kinds of words.
Burned is a verb, whereas burnt is an adjective. Burned refers to the act of burning committed in the past, and burnt refers to the quality an object has when it has undergone burning in the past.
