युगल के लिए जोड़ीदार चाहिए।

A very literal breakdown is:

• युगल = couple, pair
• के लिए = for
• जोड़ीदार = partner, counterpart, match
• चाहिए = is needed / is wanted / is required

So the structure is basically:

For the couple, a partner is needed.

Hindi often uses this kind of impersonal structure instead of wording it the same way English does.

के लिए means for.

It shows who the needed thing is intended for. So:

• युगल के लिए = for the couple

This makes the sentence sound like a requirement or announcement:

• A partner is needed for the couple

That is slightly different in feel from saying that the couple themselves actively want something.

Because के लिए is a fixed postpositional expression in Hindi.

You do not normally change it to का लिए or की लिए. The whole phrase stays के लिए, regardless of the gender of the noun before it:

• लड़के के लिए
• लड़की के लिए
• बच्चों के लिए

So युगल के लिए is just the normal form.

Because युगल is one of those nouns that often stays the same in the direct and oblique singular.

In Hindi, a noun before a postposition such as के लिए usually goes into the oblique form. But not all nouns visibly change. Since युगल ends in a consonant and is a more Sanskrit-style noun, its oblique singular usually looks the same as its basic form.

So:

• direct: युगल
• oblique singular: युगल

No visible change is needed here.

They are related, but they are not the same.

• युगल = a couple, pair, duo
• जोड़ीदार = a partner, mate, counterpart, the other member of a pair

So in this sentence:

• युगल refers to the couple/pair being talked about
• जोड़ीदार refers to the partner being sought

Because the meanings are close, the sentence can sound a little context-dependent or formal. But grammatically it is fine.

Here चाहिए means something like:

• is needed
• is wanted
• is required

It does not work exactly like the ordinary verb to want in English.

So जोड़ीदार चाहिए is not literally wants a partner in the same grammatical way as English. It is more like:

• a partner is needed
• a partner is wanted

This is a very common question.

• चाहता है comes from चाहना and means wants
• चाहिए means is needed / is wanted / should be had

Compare:

• वह पानी चाहता है = He wants water
• उसे पानी चाहिए = He needs/wants water

The second pattern is extremely common in Hindi. It is often less about a deliberate act of wanting and more about need, requirement, or desired availability.

So in your sentence, चाहिए gives the idea of requirement or need.

Because Hindi normally puts the main predicate at the end.

The basic flow here is:

• topic or beneficiary: युगल के लिए
• thing needed: जोड़ीदार
• predicate: चाहिए

So the word order feels natural in Hindi. English would usually say:

• A partner is needed for the couple

But Hindi very often saves the key predicate for the end.

Because with चाहिए, Hindi normally does not add है in this kind of present-tense statement.

For example:

• मुझे पानी चाहिए
• उसे मदद चाहिए
• युगल के लिए जोड़ीदार चाहिए

These are complete as they are.

So even though English might expect a form of is, Hindi does not normally say चाहिए है here.

Yes, but the nuance changes.

• युगल को जोड़ीदार चाहिए = The couple needs a partner
• युगल के लिए जोड़ीदार चाहिए = A partner is needed for the couple

The को version sounds more direct and personal: the couple is the experiencer of the need.

The के लिए version sounds a bit more external, like describing a requirement or search on behalf of the couple.

No. Hindi does not have articles in the same way English does.

So जोड़ीदार can mean:

• a partner
• the partner

The exact meaning depends on context.

In most contexts here, English would naturally translate it as a partner.

Yes, it sounds somewhat formal or written, mainly because of words like युगल and जोड़ीदार.

In everyday speech, people might choose simpler or more colloquial wording depending on the situation. But the sentence is grammatically correct and understandable.

So it is a good sentence for learning structure, even if it may sound a bit more formal than casual conversation.

A simple learner-friendly pronunciation guide:

• जोड़ीदार ≈ jo-dee-daar
• चाहिए ≈ chaa-hi-ye

A few details:

• In जोड़ीदार, the ड़ sound is a Hindi retroflex flap. English does not have an exact match, but a quick soft r/d-like flap is a reasonable approximation for learners.
• चाहिए is often spoken smoothly, almost like chaahiye or chaaiye, depending on the speaker.

So the whole sentence is roughly:

yugal ke liye jodidaar chahiye
