Bhojpuri grammar
Bhojpuri grammar (Bhojpuri: ) is the grammar of the Bhojpuri language. In many aspects, it is quite similar to other Eastern Indo-Aryan languages. Nouns 

Nouns in Bhojpuri have three forms, viz. short, long and redundant. Thus, for ghōṛā (Horse), the forms will be ghōṛā, ghoṛwā and ghoṛawā respectively. In some cases, the long form ends with /ē/, ghoṛwē. The redundant form has two more variants, /-ā/ and /-yā/. Thus for kukur (a dog), it can take the form kukurā and for māli (a gardener) maliyā. /-ā/ is used with nouns which have a disyllabic structure like bhatār, bhatarā ("husband") or sonār, sonarā ("goldsmith"). The suffix /-yā/ is added to nouns ending in /-i/, including feminine forms derived by adding /-i/, like bētī, betiyā ("daughter") and aurat, auratiyā ("women"). The oblique forms of nouns are identical to the nominative with the exception of verbal nouns. Definitness 
The redundant form, as it is called by Greirson, actually does the grammatical task of coding definiteness in the noun morphology. It is same as the definite articles the and la of English and French respectively. Thus, ghorawā is "the horse" and maliyā is "the gardener". Morphology 
To characterize nouns the suffixes -wala and -iya are extensively used. -wala is also used in Hindustani but its use is more extensive in Bhojpuri where it can replace the adjective-forming suffixes of borrowed words, e.g. /-dār/. For instance,  becomes ijjatwalā in Bhojpuri. The suffix /-iyā/ (also /-aiyā/, /-vaiyā/ variations) is also used extensively as characterizing suffix, as in kalkatiyā, characteristic or belonging to Kolkata, and puraniyā, characterized by old age. Gender 
The Animate nouns in Bhojpuri are gendered. Those referring to females are feminine and rest are masculine. The feminine is formed by adding /-i/, /-in/ and /-ni/ to masculine nouns, e.g. /ājā/ ("grandfather") →  /ājī/ ("grandmother") or /māli - mālin/ and /babuā - babunī/ (boy - girl). Number 
To form the plural in Bhojpuri, the final long vowel is shortened and -n, -nh or -ni is added. In some cases, nouns of multitude like sabh (all) or lōg (people) are added to nouns to make plurals. Cases 
Cases are generally formed by adding prepositions to the Nominative case or the oblique form (if exists) of the nouns. Sometimes true cases are also found, such as an Instrumental and Locative formed by adding -ē, as in Bengali. Thus, the locative and Instrumental case of ghar ("house") is ghare ("in/by the house"). These case forms are only found in the singular, however. To form the instrumental case; sē, tē, santē and kartē are also added to the noun forms, hence ghar se is to the house. To form the dative, lā, lag, khātir are added, ex:- ghar la (for the house)
 For the ablative case, sē, lē are added. Noun Phrases 
Nouns can be preceded by quantifiers. The quantifiers -gō, -ṭhō and -ṭhē are used with numeral to emphasize countability as opposed to totality. The limiter expression in Bhojpuri are marked morphologically by using the suffixes -ē and -ō, to show inclusiveness and exclusiveness respectively, as in ham āmē khāïb (I will eat only mangoes) and ham āmō khāïb (I will eat mango, too). Pronouns

Personal Pronouns
The first-person pronoun has two forms viz. inferior (mē) and superior (ham). The inferior form was used in Old Bhojpuri but is obsolete in Modern Bhojpuri and is mostly found in poetry. Ham is used as the first-person singular pronoun; the oblique form is Hamrā, however sometimes ham (ham-kē) also serves as oblique form. In the Sadri dialect, mōe is used instead of ham. In the second person, tē is used toward people younger than the speaker, to servants, and also while speaking disrespectfully. It can also show deep affection. For instance, a son always uses tē for his mother. tū is ordinarily respectful term and can be used to address anyone, whether younger or older. To show extreme respect or honour, raüwā or apnē is used. The demonstrative pronouns ī and ū are used as third-person pronouns in Modern Bhojpuri; the sē and tē of Old Bhojpuri survive but are not used frequently or mostly only in a proverbial sense. For instance, jē jaïsan karī tē taïsan pāï (lit. "Who as he does, he so obtains"). Demonstrative Pronouns 

The proximate demonstrative pronouns ("this" or "those") of Modern Bhojpuri are given in the following table. The genitive form is ēkar, hēkar, inkar, hinkar. Sometimes the suffix -i is added to them and used a feminine. The remote form of demonstrative adjectives can be made by replacing i with u and e with o in the proximate form. Thus, eknī will becomes oknī and so on. Relative Pronouns 

The relative pronoun jē in Bhojpuri is same as other Eastern Indo-Aryan languages. Other Pronouns 

 Keu, Kēhu and Kawano are used as animate forms of indefinite pronouns and kichu, kuchu, kichuo, kuchuo as inanimate forms. apanā and apne are used to show relative sense, nija is used in instrumental case. Adjectives 
Like the nouns, adjectives also have short, long and redundant forms, e.g. baṛ, baṛkā, baṛkawā. Sometimes, the suffixes -han and -har are also used with adjectives, e.g. lām - lamhar and baṛ - baṛhan. Adjectives don't agree in gender with the noun. Hence the adjective baṛ (big) is same for laïkā ("boy") and laïki ("girl"), just as in other Magadhan languages. In Bhojpuri, however, the long form with suffix /-ka/ and /-kī/ is gendered, thus baṛkā and baṛkī are used for masculine and feminine respectively. Degree of Comparison 
There are no inflexions for comparative and superlative forms. The words equivalent to "more" like besi, jiādā, dhēr and "less" like kam are used before the adjectives while comparing:

Sometime comparison is done using the numerals unaïs (nineteen) and bīs (twenty), where former is used for less and later for more. The superlative is expressed by adding sabh mē or sabh sē or sabh mē baṛhi kē or sabh se baṛhi kē (best of all) before the adjective, for example u laïka sabh mē nīk hawe (the boy is best of all). Verbs 
Chaterji has classified Bhojpuri verbs into two categories viz. primary root and secondary root. The former one are those which are inherited from Old Indo-Aryan while the latter are causitive, denominative or compounded. Like Bengali, Bhojpuri has two moods, indicative and imperative. History of Bhojpuri Grammars 
The earliest mentions of some grammatical features of Bhojpuri can he found in Buchanan's report on Shahabad in 1812. A detailed grammatical sketch of Bhojpuri was first published by Beames in 1868. In 1877, J.R. Reid tried to give a picture of the Bhojpuri spoken in Azamgarh district. Greirson's Linguistic Survey of India Vol. V, Part II, published in 1903, contained a skeleton grammar of Bhojpuri with specimens. Notes
