DIRECTIONS OF NON-SEMANTIC PHONETIC SUBSTITUTIONS IN LANGUAGE SYSTEMS

Phonetic substitutions are among the most common phenomena observed in natural languages. While in many cases such substitutions may lead to semantic shifts or misunderstandings, there exists a particular category of phonetic changes that do not alter the lexical or semantic value of words. These non-semantic phonetic substitutions, often occurring within dialectal, sociolectal, or individual speech variations, demonstrate how sound shifts can function as markers of regional, social, or stylistic diversity without impacting the core meaning of linguistic units. This article explores the directions and typologies of phonetic substitutions that remain semantically neutral across different language systems. Drawing from examples in Azerbaijani, English, and several other typologically diverse languages, the study analyzes substitution patterns, such as vowel-consonant alternations, voiced-voiceless pairings, and regional articulatory preferences. The research also discusses the implications of such substitutions for language teaching, speech recognition technologies, and sociolinguistic identity. Ultimately, this paper aims to highlight the linguistic flexibility that allows for phonetic variation without semantic disruption, shedding light on the subtle balance between sound and meaning in human communication
