Syllable weight in the context of "Poem"

Poetry (from the Greek word poiesis, "making") is a form of literary art that uses aesthetic and often rhythmic qualities of language to evoke meanings in addition to, or in place of, literal or surface-level meanings. Any particular instance of poetry is called a poem and is written by a poet. Poets use a variety of techniques called poetic devices, such as assonance, alliteration, consonance, euphony and cacophony, onomatopoeia, rhythm (via metre), rhyme schemes (patterns in the type and placement of a phoneme group) and sound symbolism, to produce musical or other artistic effects. They also frequently organize these devices into poetic structures, which may be strict or loose, conventional or invented by the poet. Poetic structures vary dramatically by language and cultural convention, but they often rely on rhythmic metre: patterns of syllable stress or syllable (or mora) weight. They may also use repeating patterns of phonemes, phoneme groups, tones, words, or entire phrases. Poetic structures may even be semantic (e.g. the volta required in a Petrachan sonnet).

Most written poems are formatted in verse: a series or stack of lines on a page, which follow the poetic structure. For this reason, verse has also become a synonym (a metonym) for poetry. Some poetry types are unique to particular cultures and genres and respond to characteristics of the language in which the poet writes. Readers accustomed to identifying poetry with Dante, Goethe, Mickiewicz, or Rumi may think of it as written in lines based on rhyme and regular meter. There are, however, traditions, such as Biblical poetry and alliterative verse, that use other means to create rhythm and euphony. Other traditions, such as Somali poetry, rely on complex systems of alliteration and metre independent of writing and have been described as structurally comparable to ancient Greek and medieval European oral verse. Much modern poetry reflects a critique of poetic tradition, testing the principle of euphony itself or altogether forgoing rhyme or set rhythm. In first-person poems, the lyrics are spoken by an "I", a character who may be termed the speaker, distinct from the poet (the author). Thus if, for example, a poem asserts, "I killed my enemy in Reno", it is the speaker, not the poet, who is the killer (unless this "confession" is a form of metaphor which needs to be considered in closer context – via close reading).

A mora (pl. morae or moras; often symbolized μ) is a smallest unit of timing, equal to or shorter than a syllable, that theoretically or perceptually exists in some spoken languages in which phonetic length (such as vowel length) matters significantly. For example, in the Japanese language, the name of the city Ōsaka (おおさか) consists of three syllables (O-sa-ka) but four morae (O-o-sa-ka), since the first syllable, Ō, is pronounced with a long vowel (the others being short). Thus, a short vowel contains one mora and is called monomoraic, while a long vowel contains two and is called bimoraic. Extra-long syllables with three morae (trimoraic) are relatively rare. Such metrics based on syllables are also referred to as syllable weight. In Japanese, certain consonants also stand on their own as individual morae and thus are monomoraic.

The term comes from the Latin word for 'linger, delay', which was also used to translate the Greek word χρόνος : chrónos ('time') in its metrical sense.

The foot is the basic repeating rhythmic unit that forms part of a line of verse in most Indo-European traditions of poetry, including English accentual-syllabic verse and the quantitative meter of classical ancient Greek and Latin poetry. The unit is composed of syllables, and is usually two, three, or four syllables in length. The most common feet in English are the iamb, trochee, dactyl, and anapaest. The foot might be compared to a bar, or a beat divided into pulse groups, in musical notation.

A metrical foot is, in classical poetry, a combination of two or more short or long syllables in a specific order; although this "does not provide an entirely reliable standard of measurement" in heavily accented Germanic languages such as English. In these languages it is defined as a combination of one stressed and one or two unstressed syllables in a specific order.

A spondee (Latin: spondeus) is a metrical foot consisting of two long syllables, as determined by syllable weight in classical meters, or two stressed syllables in modern meters. The word comes from the Greek σπονδή, spondḗ, 'libation'.

A dactyl (/ˈdæktɪl/; from Greek δάκτυλος 'finger') is a foot in poetic meter. In quantitative verse, often used in Greek or Latin, a dactyl is a long syllable followed by two short syllables, as determined by syllable weight. The best-known use of dactylic verse is in the epics attributed to the Greek poet Homer, the Iliad and the Odyssey. In accentual verse, often used in English, a dactyl is a stressed syllable followed by two unstressed syllables—the opposite is the anapaest (two unstressed followed by a stressed syllable).

An example of dactylic meter is the first line of Henry Wadsworth Longfellow's epic poem Evangeline (1847), which is in dactylic hexameter:
