Hljóðkerfi

Hljóðkerfi, or phonology, is the part of linguistics that studies the sound system of a language. It concerns the set of distinct sounds (phonemes) that can distinguish words, how those sounds are arranged in syllables and words, and the rules that govern their patterns. Phonology differs from phonetics in focusing on contrastive sound units and their abstract representations rather than on physical articulation alone.

A language’s hljóðkerfi typically includes several core components: the inventory of phonemes for vowels and consonants; patterns of allophony, where the same phoneme can have different realisations; phonotactics, which describe permissible sound sequences and syllable structures; stress, intonation, and rhythm; and phonological processes or rules that alter sounds in context, such as assimilation, deletion, epenthesis, or vowel harmony.

Analysis in phonology involves collecting linguistic data, identifying minimal pairs to establish contrastive sounds, and proposing rules or representations that capture observed patterns. The work spans different theoretical approaches, from traditional rule-based analyses to autosegmental phonology and constraint-based frameworks.

Phonology often interacts with writing systems and diachronic change. Orthography can reflect or obscure underlying phonology, and phonological systems vary across dialects and languages due to historical sound change and language contact. In Icelandic contexts, for example, hljóðkerfi is described in terms of its consonant and vowel inventories, their contrasts, and the syllable and phonotactic patterns that shape pronunciation.
