geminates

Geminates are a linguistic phenomenon referring to sounds that are held for a longer duration than their single counterparts. This doubling of a consonant sound can affect the meaning of words, distinguishing them from words with single consonants. For instance, in Italian, the difference between 'fato' (fate) and 'fatto' (fact) is solely due to the gemination of the /t/ sound. Similarly, Japanese famously uses gemination to create minimal pairs like 'kite' (come) and 'kitte' (stamp).

The phonetic realization of geminates involves a longer closure or constriction in the vocal tract. This extended duration is often perceived by listeners as a distinct sound. The process by which a geminate is formed can vary, but it typically involves a pause or a lengthening of the consonant articulation. In some languages, gemination is a phonemic feature, meaning it distinguishes meaning. In others, it might be an allophonic variation, occurring in specific phonetic environments without changing the word's meaning.

The orthography used to represent geminates also differs across languages. Some languages, like Italian, use double letters to indicate a geminate sound (e.g., 'pp', 'tt', 'kk'). Others, like Finnish, employ a similar convention. However, some languages may not explicitly represent gemination in their writing systems, relying on context or pronunciation rules. The study of geminates is crucial for understanding phonological systems and the nuances of sound production in human language.
