A syllable is a unit of organization for a sequence of speech sounds typically made up of a syllable nucleus (most often a vowel) with optional initial and final margins (typically, consonants). Syllables are often considered the phonological "building blocks" of words. They can influence the rhythm of a language, its prosody, its poetic metre and its stress patterns. Speech can usually be divided up into a whole number of syllables: for example, the word ignite is made of two syllables: ig and nite.
Syllabic writing began several hundred years before the first letters. The earliest recorded syllables are on tablets written around 2800 BC in the Sumerian city of Ur. This shift from pictograms to syllables has been called "the most important advance in the history of writing".
A word that consists of a single syllable (like English dog) is called a monosyllable (and is said to be monosyllabic). Similar terms include disyllable (and disyllabic; also bisyllable and bisyllabic) for a word of two syllables; trisyllable (and trisyllabic) for a word of three syllables; and polysyllable (and polysyllabic), which may refer either to a word of more than three syllables or to any word of more than one syllable.
Syllable is an Anglo-Norman variation of Old French sillabe, from Latin syllaba, from Koine Greek συλλαβή syllabḗ (sylːabɛ̌ː). συλλαβή means "the taken together", referring to letters that are taken together to make a single sound.
συλλαβή is a verbal noun from the verb συλλαμβάνω syllambánō, a compound of the preposition σύν sýn "with" and the verb λαμβάνω lambánō "take". The noun uses the root λαβ-, which appears in the aorist tense; the present tense stem λαμβάν- is formed by adding a nasal infix before the β b and a suffix -αν -an at the end.
In the International Phonetic Alphabet (IPA), the fullstop . marks syllable breaks, as in the word "astronomical" /ˌæs.trə.ˈnɒm.ɪk.əl/.
In practice, however, IPA transcription is typically divided into words by spaces, and often these spaces are also understood to be syllable breaks.

In phonetics, aspiration is the strong burst of breath that accompanies either the release or, in the case of preaspiration, the closure of some obstruents. In English, aspirated consonants are allophones in complementary distribution with their unaspirated counterparts, but in some other languages, notably most South Asian languages (including Indian ones) and East Asian languages, the difference is contrastive.
In phonology, liquids are a class of consonants consisting of voiced lateral approximants like /l/ together with rhotics like /r/. The grammarian Dionysius Thrax used the Ancient Greek word ὑγρός (, ) to describe the sonorant consonants (/l, r, m, n/) of classical Greek. Most commentators assume that this referred to their "slippery" effect on meter in classical Greek verse when they occur as the second member of a consonant cluster. This word was calqued into Latin as liquidus, whence it has been retained in the Western European phonetic tradition.
In phonology and linguistics, a phoneme (ˈfoʊniːm) is a unit of phone that can distinguish one word from another in a particular language. For example, in most dialects of English, with the notable exception of the West Midlands and the north-west of England, the sound patterns sɪn (sin) and sɪŋ (sing) are two separate words that are distinguished by the substitution of one phoneme, /n/, for another phoneme, /ŋ/. Two words like this that differ in meaning through the contrast of a single phoneme form a minimal pair.
