answers: Alliteration
context: International Phonetic Alphabet, long consonants are normally written using the triangular colon , e.g. "penne" ('feathers', 'pens', also a kind of pasta), though doubled letters are also used (especially for underlying phonemic forms, or in tone languages to facilitate diacritic marking). Doubled orthographic consonants do not always indicate a long phonetic consonant. Gemination In phonetics and phonology, gemination (), or consonant lengthening, is an articulation of a consonant for a longer period of time than that of a single instance of the same type of consonant. It is distinct from stress and may appear independently of it. "Gemination" literally means </s> alliteration the repetition of vowel sounds, or repetition at the end of words. Alliteration narrowly refers to the repetition of a letter in any syllables that, according to the poem's meter, are stressed, as in James Thomson's verse "Come…dragging the "l"azy "l"anguid "l"ine a"l"ong". Consonance is a broader literary device identified by the repetition of consonant sounds at any point in a word (for example, co"m"ing ho"m"e, ho"t" foo"t"). Alliteration is a special case of consonance where the repeated consonant sound is in the stressed syllable. Alliteration may also refer to the use of different but similar consonants, such as </s> couplet, and some of the traditionally rhymed stanza forms. It is used both in early forms of English poetry and in later forms. William Shakespeare famously used iambic pentameter in his plays and sonnets, as did the 20th century poet Wallace Stevens. As lines in iambic pentameter usually contain ten syllables, it is considered a form of decasyllabic verse. An iambic foot is an unstressed syllable followed by a stressed syllable. The rhythm can be written as: The da-DUM of a human heartbeat is the most common example of this rhythm. A standard line of iambic pentameter is five iambic
