टूथब्रश बाथरूम में है।

Hindi often borrows everyday nouns from English, especially for modern objects and places. In this sentence:

• टूथब्रश = toothbrush
• बाथरूम = bathroom

They are written in Devanagari, the Hindi script, but they are loanwords from English. This is very common in modern Hindi speech.

Hindi usually follows Subject–Object/Complement–Verb order, so the verb often comes at the end.

This sentence breaks down as:

• टूथब्रश = toothbrush
• बाथरूम में = in the bathroom
• है = is

So the structure is:

• Toothbrush + bathroom in + is

That is normal Hindi word order.

में means in, inside, or sometimes within.

Hindi uses postpositions, not prepositions. That means the location word comes first, and then the grammatical marker comes after it.

So:

• बाथरूम में = in the bathroom

Compare with English:

• English: in the bathroom
• Hindi: bathroom in

Because Hindi uses postpositions instead of prepositions.

In English, words like in, on, and with come before a noun:

• in the bathroom

In Hindi, the equivalent word comes after the noun:

• बाथरूम में

Other examples:

• घर में = in the house
• मेज़ पर = on the table
• उसके साथ = with him/her

है means is.

It is the present-tense form of the verb to be for a singular subject in this kind of sentence.

So in:

• टूथब्रश बाथरूम में है

  है tells you that the toothbrush is in the bathroom.

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

So टूथब्रश can mean:

• a toothbrush
• the toothbrush

The exact meaning depends on context. If the meaning shown to the learner is The toothbrush is in the bathroom, that is a natural English translation even though Hindi does not explicitly say the.

Yes, nouns in Hindi are treated as masculine or feminine, even borrowed words. But with this sentence, you do not really see much effect from that.

टूथब्रश is commonly treated as masculine by many speakers, though loanword gender can sometimes vary in actual usage.

In this sentence, the verb is है, which works for singular subjects regardless of gender in the present tense:

• वह लड़का यहाँ है = that boy is here
• वह लड़की यहाँ है = that girl is here

So even if you are unsure about the gender of टूथब्रश, this sentence still stays the same.

Because here टूथब्रश is the thing being talked about, and it does not need a postposition.

The location phrase is what gets marked:

• बाथरूम में = in the bathroom

Hindi often leaves the main noun plain unless it needs a marker such as:

• को
• से
• में
• पर

So टूथब्रश appears in its basic form.

Yes. That is also natural Hindi.

Both are possible:

• टूथब्रश बाथरूम में है
• बाथरूम में टूथब्रश है

The second version may sound a little more like you are introducing the location first: In the bathroom, there is a toothbrush or The toothbrush is in the bathroom depending on context.

Hindi word order is somewhat flexible, though the verb usually stays at the end.

में is usually pronounced roughly like mein, but with nasalization.

A helpful approximation is:

• meh̃ or main with a nasal sound

The dot-like mark above it indicates nasalization in pronunciation.

So:

• बाथरूम में sounds roughly like baa-throom mein

A rough pronunciation is:

• ṭūthbrash bāthrūm mẽ hai

Very loosely for an English speaker:

• tooth-brush baa-throom mein hai

A few notes:

• ट is a retroflex t sound, made with the tongue curled back slightly.
• थ in टूथब्रश and बाथरूम is not exactly the English th in think; in Hindi it is an aspirated t sound.
• है is often pronounced close to hai.

In standard Hindi, है is normally kept in a sentence like this. It is an important part of the sentence.

So:

• टूथब्रश बाथरूम में है = correct

If you leave out है, it may sound incomplete or nonstandard in most normal situations.

In very casual speech, people sometimes shorten things, but for learners it is best to include है.
