For example, while it takes at least four words to say "I wrote them it" in English ("I" being the subject, "it" being the direct object, "them" being the indirect object), in Georgian this can be said in one word: davuts'ere. Version marker Right after the nominal marker can come a "version" marker. Phonologically, version markers consist of any one of the vowels except for /o/. Version markers are semantically diverse. They can add either an unpredictable lexical meaning to the verb, or a functional meaning including causativity, passive voice, subjective version, objective version and locative version. For example, while v-ts'er means "I write it", v-u-ts'er means "I write it to him/her" (objective version), v-a-ts'er means "I write it on him/her" (locative version), and v-i-ts'er means "I write it (for myself)" (subjective version). Verb root The length of the verb root typically ranges from one to seven phonemes, with the longest root consisting of 15. Some consist of consonants only. The common root of the verbs meaning 'open', 'receive', 'take', and 'take a picture' is -gh-. "Lexical derivation" (or "word formation") is accomplished through the use of preverbs, version markers, and thematic suffixes. Some derivations of -gh- are seen in the sentences mi-v-i-gh-e ts'erili, 'I received the letter' and ga-a-gh-eb k'ars, 'you will open the door' (derivational affixes are bolded). Passive marker In Georgian, two morphological means of converting a transitive verb to an intransitive verb (or to passive voice) are to add -d- to the end of the verb root or to add the version marker -i- (see the discussion of version markers elsewhere in this article). Respective examples: ga-a-ts'itl-e, 'you made him blush' ( -ts'itl- is the root of ts'iteli, 'red') > ga-ts'itl-d-i, 'you blushed'; class 2 verb da-v-bad-eb, 'I will give birth to him/her', > da-v-i-bad-eb-i, 'I will be born' (the -i- at the end of the verb is the suffixal nominal marker obligatory with intransitive verbs (see below)). Thematic suffix The language has eight kinds of thematic suffixes (also sometimes known as present-future stem formants or PFSF). The suffixes are -eb-, -ev-, -av-, -am-, -i-, -ob-, -op-, and -Ø-. When the suffixal passive marker is absent, one of these suffixes can be placed right after the root of the verb. With these suffixes the verbs gain arbitrary meanings. Thematic suffixes are present in the present and future screeves, but are absent in the past and mostly
