Carpathian adjectives

Carpathian adjectives have nominal morphology, although they share some traits with inactive verbs, such as object conjugation. Unlike nouns, adjectives alternate between all four genders (masculine, feminine, common and neuter), agreed with the corresponding gender of the noun. Adjectives have three degrees of comparison: positive (no suffix: masculine dàbas, neuter dàba, feminine dàbā, common dàbis “good”), comparative (suffix -es-: masculine dabesas, neuter dabesa, feminine dabesā, common dabesis “better”) and superlative (suffix -im-: masculine dabimas, neuter dabima, feminine dabimā, common dabimis “better”). Their number agrees with the number of the corresponding nouns. Adjectives have no vocative case instead using the nominative, when necessary.

As in the case of noun paradigms, adjectives have their own classes, but there are only two: "a"-stem and "u"-stem. All other declensional classes either merged into the two, or did not exist. The masculine and neuter adjectives share all their oblique case endings, being different only in the nominative (for all numbers) and accusative (for dual and plural).

a-stem adjectives

An example of an "a"-stem adjective is jaũnas “young”.

Person markers

Carpathian adjectives can act as predicates by taking person markers. The adjectival person markers are the same as object markers of verbs and similar to possessive suffixes of nouns, all having a common origin in early Proto-Carpathian personal clitics. The category of number (singular or plural) is also indicated.

Below is the table of person markers:

	1st	2nd	3rd
			proximate	obviate
Singular	-mi	-ti	-(j)is	-tas
Dual	-nū	-wū	-(j)ī	-tai
Plural	-nas	-was	-īs	-tā

Certain case endings change their vowel quality before a marker, for example: jaunū wīrū “two young men” wīrū šī^W/sī^E jaunōjī “these two men are young” ("W" is Western Carpathian and "E" is Eastern Carpathian).
