Appendix:Finnish declension/tuhat

KOTUS type 46 (tuhat)	NSK type 76 (tuhat)

The word tuhat only, and its compound words; consonant gradation in the inflectional stem.

Declension is the same as kahdeksas, except for the ending of the nominative, and a rare genitive plural.

The final -t of the nominative is replaced by -nte- in the inflectional stem; this is subject to nt → nn consonant gradation, and becomes -ns- before the plural marker -i-.

Partitive singular ending -tta/-ttä, replacing the -t, partitive plural ending -a/-ä and standard genitive plural ending -en.
