Hindi postpositions: को, ने, से, में and पर explained

Hindi has no prepositions. It has postpositions, which do the same job but stand after the noun instead of before it: मेज़ पर is “table on”, दिल्ली से is “Delhi from”, घर में is “house in”. The five you need first are को (to), ने (the past-tense subject marker), से (from, with, by), में (in) and पर (on). Two things make them harder than they look — the noun in front of them changes form, and ने changes what the verb agrees with.

Learners usually get the meanings quickly and the two side-effects not at all. कमरा में is the single most common beginner error in written Hindi, and it is not a vocabulary mistake — the postposition is right and the noun is wrong.

The five to learn first

Because they follow the noun, a Hindi phrase reads back-to-front against English word by word — and then the verb arrives at the very end, as it always does in Hindi. The verb goes last, always covers that half of the pattern.

The noun changes shape first

Any noun standing in front of a postposition shifts into what grammars call the oblique case. For most nouns nothing visible happens, but masculine nouns ending in -आ change that ending to -ए, and every plural noun takes -ओं.

This is why कमरा में is wrong and कमरे में is right. The -आ ending marks a masculine noun standing on its own, and a postposition means it is no longer standing on its own. If the -आ / -ई gender pattern is unfamiliar, every Hindi noun has a gender explains where those endings come from.

Pronouns have their own fused forms

Pronouns do not politely take a postposition on the end — they merge with it. These forms have to be learned as vocabulary, because you cannot build them from मैं and को.

मुझे is the form doing the work in मुझे भूख लगी है and मुझे पानी चाहिए — the pattern behind Hindi has no verb for “to have”.

ने, and why it rewrites the verb

ने is the one postposition with no English counterpart at all. It marks the subject of a transitive verb in the past tense — and once it appears, the verb stops agreeing with the subject and agrees with the object instead.

Both sentences have the same speaker. खाया becomes खाई purely because रोटी is feminine and आम is masculine. Nothing about the speaker's gender enters the sentence, which is the opposite of what happens in the present tense — see Hindi verbs change with gender.

That last row is the escape hatch. When the object itself carries को, the verb cannot agree with anything, so it falls back to the default masculine singular form. मैंने लड़कियों को देखा keeps देखा even though लड़कियों is feminine plural.

ने appears only with transitive verbs — ones that take an object. Intransitive verbs never take it: मैं गया (I went), not मैंने गया. The pair to memorise is मैं गया against मैंने खाया, same speaker, same tense, different marking.

से does three unrelated jobs

The third row catches English speakers, because “meet with” and “talk with” use से where English feels like it wants को. मैं राम से बात करूँगा is “I will talk to Ram”; राम को बात करूँगा is not a sentence.

का is a postposition too, and it agrees

का marks possession, and unlike the others it changes form to match the thing possessed rather than staying fixed.

The के form is also the base for the compound postpositions, which are two words long and extremely common: के लिए (for), के साथ (with), के बाद (after), के पास (near), के बारे में (about). With a pronoun the first half becomes possessive — मेरे लिए, not मुझे लिए.

Why translation tools get this wrong

Postpositions are where machine output stops being subtly odd and starts being ungrammatical, because the errors are structural rather than lexical.

Every one of those is a single-letter difference, and every one of them is the kind of thing a reader notices immediately — the same failure mode described in why translation tools fail at Hinglish.

The short version

• The postposition goes after the noun: मेज़ पर, not पर मेज़.
• A masculine -आ noun becomes -ए in front of one: कमरा में is wrong, कमरे में is right.
• Every plural noun takes -ओं in front of one: लड़कों को, कुर्सियों पर.
• Pronouns fuse instead: मुझे, तुम्हें, उसे, हमें, उन्हें, and मैंने.
• ने marks a transitive past subject and hands verb agreement to the object.
• If the object carries को, the verb agrees with nothing and stays in its default form.
• से means from, with, by and than — four English words, one Hindi postposition.
