Tajik grammar
This article describes the grammar of the standard Tajik language as spoken and written in Tajikistan. In general, the grammar of the Tajik language fits the analytical type. Little remains of the case system, and grammatical relationships are primarily expressed via clitics, word order and other analytical constructions. Like other modern varieties of Persian, Tajik grammar is almost identical to the classic Persian grammar, although there are differences in some verb tenses. Nouns. Nouns are not marked for grammatical gender, although they are marked for number. Natural gender is usually distinguished by a change of word, like English , e.g. мурғ ("murgh") 'fowl' and хурӯс ("khurūs") 'rooster'. Alternatively the modifiers 'нар' ("nar") for male or 'мода' ("moda") for female can be pre or post-posed to the noun, e.g. хар-и нар ("khar-i nar") 'male donkey' and хар-и мода ("khar-i moda") 'female donkey'. The article does not exist, although the definite direct object is marked by a suffix, -ро ("-ro"). The use of this suffix is mandatory when a previously referenced object is being talked about. Nouns may exhibit several suffixes. Of these suffixes, the plural marker is found first, followed by any possessive markers followed  by the direct object marker. For example, in the following noun: This may be understood as [kitob [-ho "pl" [-yaton "2nd person pl." [-ro "direct object marker"] ] ] ], translation: "your (pl.) books" Number. Two forms of number exist in Tajik, singular and plural. The plural is marked by either the suffix -ҳо ("-ho") or -он ("-on"), although Arabic loan words may use Arabic forms. While -ҳо can be used with any noun, the suffix -он is primarily used with animate nouns and has the variants -ён (-yon) which is used with words ending in -ӣ, ӯ or -о, -вон (-von) for  words ending in у, and -гон (-gon) which is used with words ending in -а. For example, the singular for 'horse' is асп ("asp"), and the plural, 'horses' can be either аспҳо ("aspho") or аспон ("aspon"). Typically, the -он ("-on") ending is reserved for animate objects, although this is not always true. For example, body parts that come in pairs, such as даст ("dast"), meaning "hand" and чашм ("chashm"), meaning "eye" are pluralized as дастон ("daston") and чашмон ("chashmon"), respectively. For words ending in ӣ, the ӣ is shortened to и before suffixes Irregular plurals from Arabic exist in a  fair number of words, though—due to the lesser influence of Arabo-Islamic learning in modernity—these tend to be less widely used in Tajik than in other varieties of Persian. Adjectives. There is no agreement of the adjective, or modifier with the head word. Adjectives do not take the plural markers -он or -ҳо. Typically, adjectives follow the nouns they modify, and are linked with the izafet construction (called izofa in Tajik), for example: китоби хуб ("kitobi khub", good book) and китобҳои хуб ("kitobhoi khub", good books). However, the superlative typically precedes the noun. For example, Comparative forms use  the suffix '-тар' ("-tar"), while superlative forms use the suffix '-тарин' ("-tarin"). Izofa-construction. The izofa-construction (from изофа, اضافه, meaning 'addition') is the name given to the combination of a head word and a modifier (for example an adjective) using the unstressed enclitic, -и, ("-i"). In the plural, the enclitic is placed after the plural marker. Pronominal enclitics and the definite marker are placed at the end of the izafet-construction, for example, китоби хубам ("kitobi khubam"), "my good book". Pronouns. Forms of the personal pronouns with English language equivalent(s). The 2nd person plural, "шумо" also finds use as  the polite form of the 2nd person. In written Tajik, this polite usage is distinguished by the capitalisation of the term шумо, for example, Шумо кай меоед? ("shumo kay meoed?"), trans. "when are you coming?" vs. шумо кай меоед?, trans. "when are you (all) coming?" ***Note in Northern Dialects of Tajik, the plural form of шумо is шумоён (shumoyon) and is conjugated as кай шумоён меоедетон? ("kay shumoyon meoyedeton?") or "when are you all coming?" Enclitic forms. There are enclitics used after words to denote possession. For example: китоб ("kitob", "book"), китобам ("kitobam", "my book"), китобат ("kitobat", "your book"). When  following a vowel, for example китобҳо ("kitobho", books), the leading '-а' is changed to '-я'. The phrase "their books", would be китобҳояшон ("kitobhoyashon"). Verbs. Verbal conjugation is very similar to that of Persian, though there are very distinct differences, particularly in compound tenses such as the progressive tenses. Infinitives and stems. Infinitives end in -тан (-tan) or -дан (-dan). The principal parts to remember are the past stem and present stem. The past stem is the easier to recognize, as it is determined simply by removing the -ан from the infinitive. The present stem tends to vary more, and in  many common verbs bears little resemblance to the infinitive or past stem. In some verbs, the present stem is identical to the past stem, but for the -t/-d. Participles. Tajik has two participles - past and present. The past participle is formed by adding -а to the past stem The present participle is formed by adding -анда to the present stem Personal forms. Personal forms of verbs are formed mostly with simple prefixes and suffixes. Prefixes tend to be modal, while the suffixes are personal. The personal suffixes are: The most important and common prefix is the progressive ме- (me-) which  forms imperfective tenses. Instructions for forming various tenses will be given below with example conjugations of the verb кардан. An example translation will be given for the 1st person singular to give a basic idea of the tense's use. Simple past. The simple past is formed with the past stem and personal endings. Present imperfect. The present imperfect is formed by prefixing ме- to the present stem with personal endings Past imperfect. The past imperfect is formed by prefixing ме- to the simple past Present perfect. The present perfect is formed by adding the personal suffixes to the past  participle. Pluperfect. The pluperfect is a compound tense formed from the past participle and the simple perfect of the verb будан (to be) Present and past progressive. The progressives are compound tenses. The present progressive is formed with the past participle and the present perfect of the verb истодан. Similarly, the past progressive is formed with the past participle and the pluperfect of истодан. Present subjunctive. The present subjunctive is formed from the present stem with personal endings. The subjunctive is different from other forms in that it is frequently dependent on another verb. In this example, the subjunctive form  кунам is dependent on мехоҳам (I want). As such, the subjunctive alone does not translate easily into English and the translation is heavily dependent on the context of the sentence.
