अब जोड़ीदार की बारी है।

Because का / की / ke agree with the noun that comes after them — the thing being possessed — not with the possessor.

Here, the possessed noun is बारी (turn), and बारी is feminine singular, so Hindi uses की:

• जोड़ीदार की बारी
• literally: the partner’s turn

Compare:

• राम का घर = Ram’s house (घर is masculine singular)
• राम की किताब = Ram’s book (किताब is feminine singular)
• राम के दोस्त = Ram’s friends (दोस्त is plural)

So in this sentence, की is chosen because of बारी, not because of जोड़ीदार.

बारी means turn, chance, or one’s go in a sequence.

It is very commonly used when people are taking turns:

• मेरी बारी है। = It’s my turn.
• तुम्हारी बारी है। = It’s your turn.
• अब उसकी बारी है। = Now it’s his/her turn.

So बारी is the key word that expresses the idea of whose turn it is.

जोड़ीदार means partner, pair-mate, or sometimes the person paired with you.

Depending on context, it could mean:

• a game partner
• a work partner
• a dance partner
• a teammate in a pair activity

So in a classroom, game, or exercise situation, जोड़ीदार often means the person you are paired with.

It can be used for either a male or a female partner, depending on context.

This is useful for learners, because you might expect a separate masculine/feminine form, but जोड़ीदार often works as a common-gender noun in actual use.

Also, remember: in जोड़ीदार की बारी, the की is not telling you the gender of जोड़ीदार. It is agreeing with बारी.

Because Hindi often uses a structure that is different from English.

The sentence is built like this:

• अब = now
• जोड़ीदार की = of the partner / the partner’s
• बारी = turn
• है = is

So Hindi expresses the idea as Now the partner’s turn is, while natural English says Now it’s the partner’s turn.

This is very normal in Hindi. You do not need a separate word for it here.

Because Hindi often does not use a dummy subject like English it.

English needs it in sentences like:

• It is my turn
• It is late
• It is raining

Hindi usually does not need that kind of placeholder subject. So:

• मेरी बारी है।
• देर हो गई है।
• बारिश हो रही है।

So अब जोड़ीदार की बारी है। is already a complete and natural sentence without any extra pronoun.

अब means now.

It tells you that the turn has changed at this point. It is often used when giving instructions or moving from one person to another:

• अब तुम्हारी बारी है। = Now it’s your turn.
• अब मेरी बारी है। = Now it’s my turn.
• अब जोड़ीदार की बारी है। = Now it’s the partner’s turn.

So अब sets the timing: from this moment on.

Yes. That would also be natural in many contexts.

Some similar words are:

• साथी = companion, partner, teammate
• जोड़ीदार = partner, the person paired with someone
• पार्टनर = partner, borrowed from English

Which one sounds best depends on context:

• जोड़ीदार strongly suggests someone in a pair
• साथी is broader and can mean companion/teammate/classmate-partner
• पार्टनर is common in modern speech too

So अब साथी की बारी है and अब जोड़ीदार की बारी है can both work, but जोड़ीदार especially fits pair activities.

This is a very common confusion.

• बार usually means time/occasion as in once, twice, many times
• बारी means turn/chance in sequence

Examples:

• मैं वहाँ दो बार गया। = I went there twice.
• अब मेरी बारी है। = Now it’s my turn.

So in this sentence, बारी is correct because the idea is turn-taking, not number of times.

A little, yes — but the original order is the most natural.

Standard order:

• अब जोड़ीदार की बारी है।

You might also hear emphasis changes in speech, but beginners should stick with the normal pattern:

time word + possessor + possessed noun + है

So a good model is:

• अब मेरी बारी है।
• अब तुम्हारी bārī hai.
• अब जोड़ीदार की बारी है।

That pattern is very common and worth memorizing.

If you mean the partners’ turn, the possessive would usually change to की or की बारी? The key thing is still that बारी is feminine singular, so the possessive marker stays tied to बारी.

For example:

• साथियों की बारी है। = It’s the partners’ turn.
• बच्चों की बारी है। = It’s the children’s turn.

Here की is still used because बारी is still feminine singular.

This is another good reminder that का/की/के follow the gender/number of the possessed noun, not the possessor.

A simple pronunciation guide is:

jo-ree-daar

More carefully:

• जो = jo
• ड़ी = ṛī (a retroflex r sound)
• दार = dār

And बारी is roughly:

baa-ree

So the whole sentence sounds approximately like:

ab joṛīdār kī bārī hai

If you want to sound more natural, keep की बारी flowing together smoothly: ... kī bārī hai.
