of the adjective ends with a consonant or a vowel: a vowel-final-stem adjective is identical in all cases, while a consonant-final-stem adjective changes from case to case. (Put another way, one might say that vowel-final-stem adjectives do not actually decline for case.) The following table presents declensions of the adjectives did- ("big") and ch'aghara- ("grey-haired") with the noun datv- ("bear"). While often used as modifiers, adjectives can also have stand-alone substantive force in Georgian: one could say mindoda lurji ts'igni ("I would like the blue book") or just mindoda lurji ("I would like the blue one"). Possessive adjectives The possessive adjectives (equivalent to English my, your, etc.) are declined like other consonant-stem-final adjectives, except for a final -s in the dative, instrumental, and adverbial forms of the first- and second-person possessive adjectives. There are no second- and third-person vocative forms. Adpositions Georgian by and large has postpositions rather than prepositions. Most of these are cliticized to the ends of nouns. They might be written separately or together with the noun. Prepositions do exist, but they are very few in number, and tend to be calques from Russian that entered the language during the Soviet period. Each postposition governs (requires) a specific case of the noun, akin to the usage of prepositions in German or Latin. Only one postposition governs the nominative case (-vit "like"), and there are no postpositions that govern the ergative or the vocative cases. Here are some examples of postpositions: ¹ The postposition -vit could also take the dative case in its elongated form (with an insertion of -a- in between the case suffix and the postposition). ² In the usage of postposition -shi the dative case suffix -s is dropped. ³ In the usage of postposition -mde the adverbial case suffix -d is dropped. 4 In the usage of postposition -dan the instrumental case suffix -t is dropped. Examples The Georgian nominal has a series of morpheme slots that must be filled in a specific order: noun root + plural suffix + case suffix (+ postposition) Verbal system The Georgian verbal system is extremely complex, especially when compared to those of most Indo-European languages. Rather than using the terms "tense", "aspect", "mood", etc. separately, linguists prefer to use the term "screeve" to distinguish between different time frames and moods of the verbal system. A screeve is a set of six verb forms inflected for person and
