burn
The word "burn" can be used as both a verb and a noun. When used as a verb, it can be transitive (meaning you are doing the action to something else) or intransitive (meaning the subject is experiencing the action). In modern slang, "a burn" can also refer to a clever insult directed at someone, though this is informal and different from the physical injury definition. Note that "burnt" is often used as the adjective form (e.g., "burnt toast"), while "burned" is more common as the past tense verb in American English.
