A foot is the basic unit of meter in poetry, and it typically consists of two or three syllables, with a specific pattern of stressed and unstressed syllables. Some common types of feet include:
* Iamb: Unstressed, stressed (e.g., "again")
* Trochee: Stressed, unstressed (e.g., "happy")
* Spondee: Stressed, stressed (e.g., "heartbreak")
* Dactyl: Stressed, unstressed, unstressed (e.g., "happily")
* Anapest: Unstressed, unstressed, stressed (e.g., "understand")
The number of feet in a line of poetry determines the meter of that line. For example, a line with five iambs is called iambic pentameter, a line with four trochees is called trochaic tetrameter, and so on.
