प्रतिद्वंद्वी मेरे जोड़ीदार के सामने है।

Hindi does not usually use articles like the and a/an the way English does.

So प्रतिद्वंद्वी can mean:

• the opponent
• an opponent
• sometimes just opponent

The exact choice in English depends on context. In this sentence, the opponent is a natural translation.

A word-by-word breakdown is:

• प्रतिद्वंद्वी = opponent, rival
• मेरे = my
• जोड़ीदार = partner, pair-partner
• के सामने = in front of, opposite, facing
• है = is

So the structure is basically:

Opponent + my partner + in front of + is

Hindi often puts the verb at the end.

This is a very common question.

The short answer: because जोड़ीदार is followed by a postposition, it goes into the oblique case, and that affects मेरा/मेरी/मेरे.

Compare:

• मेरा जोड़ीदार = my partner
• मेरे जोड़ीदार के सामने = in front of my partner

Why?

• मेरा is used with a masculine singular noun in the direct form.
• When that noun is followed by a postposition like के सामने, it becomes oblique.
• For masculine singular oblique, मेरा changes to मेरे.

So:

• direct: मेरा जोड़ीदार
• oblique: मेरे जोड़ीदार के सामने

के सामने is a very common Hindi expression meaning:

• in front of
• opposite
• facing
• sometimes before in a more situational sense

In this sentence, the most natural meaning is in front of or opposite.

Important: के सामने works as a unit.
The के here is part of the postpositional phrase, not a separate word you should translate by itself as of.

Examples:

• घर के सामने = in front of the house
• मेरे सामने = in front of me
• उसके सामने = in front of him/her

No.

जोड़ीदार means someone who forms a pair with another person. Depending on context, it can mean:

• partner
• teammate
• dance partner
• game partner
• spouse or romantic partner

So the exact English meaning depends on the situation. In your sentence, partner is the safest general translation.

है means is.

The sentence is describing location, so Hindi uses a structure like:

X + Y के सामने + है

That means: X is in front of Y

So:

• प्रतिद्वंद्वी = the opponent
• मेरे जोड़ीदार के सामने = in front of my partner
• है = is

Also, है is singular. That matches a singular subject: प्रतिद्वंद्वी = one opponent.

Because Hindi does not need to mention posture unless it matters.

English often says:

• The opponent is standing in front of my partner

But Hindi can simply say:

• प्रतिद्वंद्वी मेरे जोड़ीदार के सामने है।

That already tells you the location.

If you specifically want to say standing, you could say:

• प्रतिद्वंद्वी मेरे जोड़ीदार के सामने खड़ा है।
  = The opponent is standing in front of my partner.

So the original sentence is more neutral: it tells location, not posture.

Yes, Hindi word order is more flexible than English.

The given sentence:

• प्रतिद्वंद्वी मेरे जोड़ीदार के सामने है।

A different but still natural order:

• मेरे जोड़ीदार के सामने प्रतिद्वंद्वी है।

Both can mean the same thing. The difference is mainly emphasis.

• Starting with प्रतिद्वंद्वी puts focus on the opponent
• Starting with मेरे जोड़ीदार के सामने puts more focus on the location

In both versions, है usually stays at the end.

Here it is singular, because the verb is है = is.

If it were plural, you would usually use हैं:

• प्रतिद्वंद्वी मेरे जोड़ीदार के सामने हैं।
  = The opponents are in front of my partner.

One thing that can confuse learners: some Hindi nouns, especially more formal Sanskrit-derived ones like प्रतिद्वंद्वी, do not always change form much between singular and plural in the direct case. So the verb often helps you tell the difference.

A helpful transliteration is:

pratidvandvī mere joṛīdār ke sāmne hai

A rough pronunciation guide:

• प्रतिद्वंद्वी = pruh-ti-dvund-vee
• मेरे = meh-ray
• जोड़ीदार = jo-ree-daar, with ड़ sounding like a soft flapped r
• के = kay
• सामने = saam-nay
• है = hai, roughly like heh or hai depending on accent

A smoother full reading: pratidvandvī mere joṛīdār ke sāmne hai

Sometimes in context, सामने can suggest being opposite someone in a contest or face-to-face situation, so an English speaker might feel against in the background.

But grammatically, के सामने literally means:

• in front of
• opposite
• facing

So in this sentence, the core idea is physical or positional opposition, not the abstract English preposition against.

If you specifically wanted against in the sense of competing against someone, Hindi would often use other wording depending on context.
