Phonotactics refers to the study of permissible sequences of phonemes within a language. It is a subfield of phonology that deals with the rules governing how sounds can be combined to form syllables and words. These rules are language-specific, meaning that what is considered a valid sound sequence in one language may be unpronounceable or nonsensical in another. For instance, in English, consonant clusters like "str" at the beginning of a word are common (e.g., "street"), while in Japanese, such clusters are generally not allowed, and a vowel is often inserted to break them up (e.g., "sutorīto" for "street").

The principles of phonotactics dictate constraints on the number and types of consonants and vowels that can appear together. This includes rules about which consonants can occur at the beginning or end of a word, as well as restrictions on which consonants can be adjacent to each other. For example, many languages do not permit voiceless stops like /p/, /t/, /k/ to appear next to each other in certain positions. Phonotactic rules also govern the structure of syllables, specifying the onset (initial consonant(s)), nucleus (vowel), and coda (final consonant(s)). Understanding phonotactics is crucial for language acquisition, speech perception, and the development of speech technology. It helps explain why certain mispronunciations occur and how speakers intuitively avoid creating forbidden sound combinations.
