मेरे जोड़ीदार का स्कोर दस है।

A natural breakdown is:

• मेरे = my
• जोड़ीदार = partner / teammate / counterpart
• का = possession marker, like of or 's
• स्कोर = score
• दस = ten
• है = is

So the literal order is roughly:

my partner's score ten is

That is normal in Hindi, because है usually comes at the end.

Because जोड़ीदार is followed by the postposition का, so it is in the oblique case.

In Hindi, मेरा / मेरे / मेरी change form depending on gender, number, and case.

For a masculine singular noun:

• मेरा = direct form
• मेरे = oblique form

Since the phrase is मेरे जोड़ीदार का..., the noun जोड़ीदार is not standing alone; it is followed by का, so मेरे is the correct form.

So:

• मेरा जोड़ीदार = my partner
• मेरे जोड़ीदार का = of my partner / my partner's

का marks possession. It works like English 's or of.

So:

• जोड़ीदार का स्कोर = the partner's score or the score of the partner

In this sentence, का connects जोड़ीदार with स्कोर.

Because का / की / के agree with the thing being possessed, not with the possessor.

Here, the possessed thing is स्कोर, and स्कोर is treated as masculine singular, so Hindi uses का.

Compare:

• जोड़ीदार का स्कोर = partner's score
• जोड़ीदार की किताब = partner's book
• जोड़ीदार के अंक = partner's marks

So in your sentence, का matches स्कोर.

जोड़ीदार usually means partner, but the exact meaning depends on context.

It can mean things like:

• teammate
• playing partner
• work partner
• pair-partner
• spouse, in some contexts

So if this sentence appeared in a game or test context, मेरे जोड़ीदार would most likely mean my partner or my teammate.

Because Hindi usually puts the verb, including to be, at the end of the sentence.

English:

• My partner's score is ten.

Hindi:

• मेरे जोड़ीदार का स्कोर दस है।

This is a very common Hindi pattern:

• topic/subject first
• description or complement next
• verb last

So दस है = is ten, but in Hindi the order is reversed.

Hindi does not normally use articles the way English does.

English often requires:

• a
• an
• the

Hindi usually leaves them out and relies on context.

So मेरे जोड़ीदार का स्कोर दस है is perfectly complete without any separate word for the or a.

If Hindi needs extra emphasis or specificity, it may use words like:

• एक = one / a
• यह = this
• वह = that

But in a normal sentence like this, no article is needed.

It is an English loanword that is commonly used in Hindi, especially in sports, games, school, and exams.

Modern Hindi freely uses many English-origin words, especially for everyday topics. So स्कोर sounds very natural in the right context.

You might also hear other words depending on the situation, such as:

• अंक = marks / points
• नंबर = number / marks

But स्कोर is completely normal.

Because basic numbers like दस are generally invariable in Hindi.

They do not change for:

• gender
• number
• case

So दस stays दस whether the noun is masculine, feminine, singular, or plural.

That is why you simply say:

• स्कोर दस है
• राशि दस है
• अंक दस हैं depending on the rest of the sentence

The number itself usually stays the same.

Not exactly. The Hindi sentence literally says:

My partner's score is ten.

That describes the score as a state or fact.

If you wanted to say My partner got ten points, Hindi would usually use a different structure, such as one built around मिले, आए, or मिला depending on context.

So your sentence is best understood as a statement about the score, not about the act of receiving it.
