almost all uralic languages, such as finnish, hungarian and estonian have a distinctive moraic chroneme as a phoneme (also arguably called archiphoneme or epenthetic vowel/consonant). the etymology of the vocalic chroneme has been traced to a voiced velar fricative in the hypothetical proto-uralic language, such that becomes . for example, "taka-" "back-", "takka" "fireplace" and "taakka" "burden" are unrelated words. it is also grammatically important; the third person marker is a chroneme ("menee" "s/he goes"), and often in the spoken finnish of the helsinki area there are grammatical minimal pairs, e.g. nominative "stadi" "helsinki" vs. partitive "stadii" "at helsinki".
