The linguistic principles used to determine where syllables begin and end
Consonant-Vowel (CV)
Syllables are generally formed around vowel sounds, with consonants preceding them forming the onset.
Vowel-Consonant (VC)
When a vowel is followed by a consonant within a word, a syllable break often occurs.
Avoidance of Complex Onsets/Codas
English tends to avoid overly complex syllable structures, favoring simpler CV patterns.

What is hyphenation
Hyphenation is the process of splitting words into syllables and inserting hyphens between them to facilitate the reading of a text. It is also used to divide words when the word cannot fit on a line.
This technique is particularly helpful in fully justified texts, where it aids in creating a uniform edge along both sides of a paragraph. Hyphenation rules vary among languages and even among different publications within the same language. It's a critical component in typesetting, significantly influencing the aesthetics and readability of printed and digital media. For instance, in compound adjectives like 'long-term solution', hyphens clarify relationships between words, preventing misinterpretation. Moreover, hyphenation can alter meanings: 'recreation' differs from 're-creation'.
With the advent of digital text, hyphenation algorithms have become more sophisticated, though still imperfect, sometimes requiring manual adjustment to ensure accuracy and coherence in text layout. Understanding and correctly applying hyphenation rules is therefore not only a matter of linguistic accuracy but also a key aspect of effective visual communication.
