in finnish, estonian and sami languages, there are also two allophonic lengths of the chroneme, "half-long" and "over-long". for example, finnish imperative "anna!" "give!" has a short vowel, "oma "own" has a half-long vowel, and "annaa "at anna" has an overlong vowel (without any distinctive tonal variation to distinguish these three). estonian and sami also have a three-way distinction in consonants, e.g. "lina" "bed sheet", "linna" (half-long 'n') "of the city", "linna" (over-long 'n') "to the city". estonian, in which the phonemic opposition is the strongest, uses tonal contour as a secondary cue to distinguish the two; "over-long" is falling as in other finnic languages, but "half-long" is rising.
