Syllabification

Syllabification () or syllabication (), also known as hyphenation, is the separation of a word into syllables, whether spoken, written or signed.

Overview

The written separation into syllables is usually marked by a hyphen when using English orthography (e.g., syl-la-ble) and with a period when transcribing the actually spoken syllables in the International Phonetic Alphabet (e.g., [ˈsɪl.ə.bᵊɫ]). For presentation purposes, typographers may use an interpunct (Unicode character U+00B7, e.g., syl·la·ble), a special-purpose "hyphenation point" (U+2027, e.g., syl‧la‧ble), or a space (e.g., syl la ble).

At the end of a line, a word is separated in writing into parts, conventionally called "syllables", if it does not fit the line and if moving it to the next line would make the first line much shorter than the others. This can be a particular problem with very long words, and with narrow columns in newspapers. Word processing has automated the process of justification, making syllabification of shorter words often unnecessary.

In some languages, the spoken syllables are also the basis of syllabification in writing. However, possibly due to the weak correspondence between sounds and letters in the spelling of modern English, written syllabification in English is based mostly on etymological or morphological, instead of phonetic, principles. For example, it is not possible to syllabify "learning" as lear-ning according to the correct syllabification of the living language. Seeing only lear- at the end of a line might mislead the reader into pronouncing the word incorrectly, as the digraph ea can hold many different values.
