Editing Consonant gradation (section)

===Northern Sami===
{{main|Northern Sami#Consonant gradation}}
[[Northern Sami language|Northern Sami]] has a system of three phonological lengths for consonants, and thus has extensive sets of alternations. Quantity 3 is represented as lengthening of the coda part of a geminate or cluster, which is absent in quantity 2. Quantity 1 consists of only an onset consonant, with the preceding syllable having no coda. In addition, most dialects of Northern Sami feature ''coda maximisation'', which geminates the last member of a cluster in various environments (most commonly in two-consonant clusters of quantity 2, in which the first member is voiced).

Most sonorants and fricatives are only subject to quantitative gradation, but nasals, stops, affricates and the glide {{IPA|/j/}} are subject to both quantitative and qualitative changes. Some words alternate between three grades, though not all words do. Note that the following apostrophe marking the over-long grade is not used in the official orthography, although it is generally found in dictionaries.

Some gradation triads include the following:
