Two or more consonant sounds may appear sequentially linked or clustered as either identical consonants or homorganic consonants that differ slightly in the manner of articulation, as when the first consonant is a
fricative and the second is a
stop. In some languages, a syllable-initial homorganic sequence of a stop and a nasal is quite uncontroversially treated as a sequence of two separate segments; and the separate status of the stop and the nasal is quite clear. In
Russian, the stop + nasal sequences are just one of the possible types amongst many different syllable-initial consonant sequences that occur. In English, nasal + stop sequences within a
morpheme must be homorganic.
Consonant length In languages as diverse as
Arabic,
Tamil and
Icelandic, there is a phonological contrast between long and short consonants, which are distinguishable from consonant clusters. In
phonetics,
gemination happens when a spoken
consonant is pronounced for an audibly longer period of time than a short
consonant. Consonant length is distinctive in some languages. In
Japanese, for example, 来た (kita) means 'came; arrived', while 切った (kitta) means 'cut; sliced'. The romanization or
transliteration of the sound of each Japanese word produces the misleading impression of a doubled consonant. ==See also==
