Meter is a unit of rhythm in poetry, the pattern of the beats. It is also called a foot. Each foot has a certain number of syllables in it, usually two or three syllables. The difference in types of meter is which syllables are accented and which are not.
anapestic (anapest): a metrical foot containing three syllables—the first two are unstressed, while the last is stressed
dactylic (dactyl): a metrical foot containing three syllables—the first is stressed, while the last two are unstressed
falling meter: meter containing metrical feet that move from stressed to unstressed syllables
iambic (iamb): a metrical foot containing two syllables—the first is unstressed, while the second is stressed
iambic pentameter: a traditional form of rising meter consisting of lines containing five iambic feet (and, thus, ten syllables)
pause (caesura): a pause for a beat in the rhythm of the verse (often indicated by a line break or a mark of punctuation)
rising meter: meter containing metrical feet that move from unstressed to stressed syllables
spondee: a nontraditional metrical foot in which two consecutive syllables are stressed
stress: greater amount of force used to pronounce one syllable over another
trochaic (trochee): a metrical foot containing two syllables—the first is stressed, while the second is unstressed
alliteration: the repetition of consonant sounds, particularly at the beginning of words
Example: ". . . like a wanderer white”
allusion: a reference to a person, event, or work outside the poem or literary piece
Example: “Shining, it was Adam and maiden”
assonance: the repetition of similar vowel sounds
Example: “I rose and told him of my woe”
consanance: the repetition of similar consonant sounds
Example: “Tyger Tyger, burning bright”
elision: the omission of an unstressed vowel or syllable to preserve the meter of a line of poetry
Example: “Th’ expense of spirit in a waste of shame”
imagery: word or sequence of words representing a sensory experience (visual, auditory, olfactory, tactile, and gustatory)
Example: “bells knelling classes to a close” (auditory)
irony: a contradiction of expectation between what is said and what is meant (verbal irony) or what is expected in a particular circumstance or behavior (situational), or when a character speaks in ignorance of a situation known to the audience or other characters (dramatic)
Example: “Time held me green and dying / Though I sang in my chains like the sea”
onomatopoeia: the use of words to imitate the sounds they describe
Example: “crack” or “whir”
