यह तोहफ़ा चुनो।

A natural transliteration is yah tohfā chuno.

A few pronunciation notes:

• यह is written yah, but in everyday speech it often sounds closer to yeh.
• तोहफ़ा means gift. The फ़ is meant to be an f sound, though many speakers say something closer to ph/f and may even write फ instead.
• चुनो is pronounced roughly chu-no.

So in careful speech you might hear yah tohfā chuno, and in casual speech something like yeh tohfa chuno.

Word by word:

• यह = this
• तोहफ़ा = gift / present
• चुनो = choose

The structure is very normal for Hindi: object + verb.

So Hindi says, literally, something like this gift choose, where the verb comes at the end.

चुनो is the imperative form of चुनना (to choose) used with तुम.

That means it is a command or instruction directed at:

• one person informally, or
• more than one person in a familiar way.

It is less formal than आप forms, and less abrupt/intimate than the bare तू form.

Compare:

• चुन — very intimate / very blunt
• चुनो — familiar, normal informal command
• चुनिए / चुनिये — polite
• चुन लीजिए — very natural polite suggestion/request

So यह तोहफ़ा चुनो sounds like speaking informally to someone: Choose this gift.

In Hindi, commands often leave out the subject because it is understood.

So:

• यह तोहफ़ा चुनो already means You choose this gift or Choose this gift
• You do not need to say तुम

If you add the subject, it usually adds emphasis:

• तुम यह तोहफ़ा चुनो = You choose this gift

That can sound contrastive, as if distinguishing one person from someone else.

Hindi does not have articles like English a, an, and the.

Instead, definiteness usually comes from context or from words like यह (this) and वह (that).

So:

• यह तोहफ़ा already clearly means a specific gift: this gift
• There is no need for a separate word like the

If you said just तोहफ़ा चुनो, context would decide whether English would translate it as choose a gift or choose the gift.

In everyday speech, many speakers do use ये where formal written Hindi would use यह.

So colloquially, you may hear:

• ये तोहफ़ा चुनो

But in standard written Hindi:

• यह = this
• ये is usually associated with plural these or certain oblique/colloquial uses

So for learning and for careful writing, यह तोहफ़ा चुनो is the safest standard form.

Yes, तोहफ़ा is a common and natural everyday word.

Other options include:

• उपहार — more formal or more Sanskrit-based
• भेंट — often used in more formal, literary, or special contexts

So:

• तोहफ़ा sounds everyday and conversational
• उपहार sounds more formal

Also, you may see तोहफ़ा written as तोहफा. The version with फ़ shows the f sound more explicitly, but both spellings are seen.

Not much in this sentence.

तोहफ़ा is a masculine noun, but the imperative verb चुनो does not change to match the noun's gender.

So whether the object were masculine or feminine, the command form चुनो would stay the same.

Gender matters more in other kinds of sentences, especially with:

• adjectives
• past-tense verbs
• participles

But in यह तोहफ़ा चुनो, the main thing to notice is the imperative, not gender agreement.
