हम आज प्लान तय करेंगे।

हम means we.

In Hindi, the subject is often included, especially when you want to be clear about who is doing the action. So हम आज प्लान तय करेंगे clearly means we will decide/finalize the plan today.

In conversation, Hindi sometimes drops the subject if it is already obvious from context:

• आज प्लान तय करेंगे। = We’ll decide the plan today.

But including हम sounds perfectly natural.

आज means today.

Hindi word order is flexible, but the most common neutral order is:

• Subject + time + object + verb

So:

• हम = we
• आज = today
• प्लान = plan
• तय करेंगे = will decide/finalize

That is why आज comes before प्लान here.

You may also hear variations for emphasis, such as:

• आज हम प्लान तय करेंगे।
• प्लान हम आज तय करेंगे।

These are still grammatical, but the focus changes slightly.

प्लान is a very common English loanword in Hindi. In everyday speech, many speakers naturally say प्लान instead of a more Sanskrit-based or formal Hindi word like योजना.

So both are possible, but they feel different in tone:

• प्लान = everyday, modern, conversational
• योजना = more formal, more purely Hindi, sometimes more official

For example:

• हम आज प्लान तय करेंगे। = natural in casual speech
• हम आज योजना तय करेंगे। = understandable, but less casual

तय means something like fixed, settled, or decided.

In this sentence, it appears in the common expression:

• तय करना = to decide, to settle, to finalize

So प्लान तय करना means to decide/finalize the plan.

This is slightly different from simply thinking of a plan. It suggests the plan is being settled or confirmed.

This is a very common Hindi pattern.

Here, the action is expressed through a combination:

• तय = decided/fixed
• करेंगे = will do

Together:

• तय करेंगे = will decide/finalize

Hindi often uses this kind of structure, where a noun, adjective, or participle combines with करना to form a verbal expression.

Some similar examples:

• शुरू करना = to begin
• खत्म करना = to finish
• साफ़ करना = to clean
• तय करना = to decide/finalize

So you should think of तय करना as one unit of meaning.

करेंगे is the future form of करना (to do).

Here it tells you:

• the action is in the future
• the subject is we (or sometimes they or formal you, depending on context)

With हम, करेंगे means we will do.

So:

• हम करेंगे = we will do

In this sentence, it combines with तय:

• हम प्लान तय करेंगे = we will decide/finalize the plan

No, not in this sentence.

With हम, the future form करेंगे does not change for masculine vs. feminine speakers. So both men and women can say:

• हम आज प्लान तय करेंगे।

That is different from some other Hindi verb forms where gender does matter more clearly.

Because प्लान is the direct object of तय करना, and direct objects in Hindi do not always take को.

Here:

• प्लान तय करना = to decide/finalize the plan

That is the normal structure.

Using को here would sound unnatural in most standard usage:

• natural: प्लान तय करेंगे
• unnatural here: प्लान को तय करेंगे

So this is just how the verb expression usually works.

A good way to break it down is:

• हम = we
• आज = today
• प्लान = plan
• तय करेंगे = will decide/finalize

Literal order:

• We today plan will-finalize

Natural English order:

• We will finalize the plan today.

Hindi normally puts the main verb at the end, which is one of the biggest differences from English.

तय is usually pronounced roughly like tay or ta-ya, depending on speed and accent.

A simple learner-friendly approximation is:

• तय ≈ tuy / tay

But the most important thing is to recognize it as the common word in तय करना.

The whole sentence can be approximated as:

• ham aaj plan tay karenge

Not exactly.

प्लान तय करेंगे usually means:

• we will decide the plan
• we will finalize the plan
• we will settle the plan

If you want to say we will make a plan today, Hindi would more naturally use something like:

• हम आज प्लान बनाएँगे। = We will make a plan today.

So:

• बनाना = to make
• तय करना = to decide/finalize

Usually, हम means we.

However, in some regional dialects or styles of speech, speakers may use हम for I. That is not the usual standard-Hindi meaning for a beginner to assume.

In this sentence, you should understand हम as normal plural we.

It is fairly neutral and natural.

Why?

• हम is neutral
• आज is neutral
• प्लान is conversational and modern
• तय करेंगे is standard and polite-neutral

So the whole sentence sounds like normal everyday Hindi. It is neither extremely formal nor slangy.

If you replaced प्लान with योजना, it would sound more formal.

Yes. Hindi often becomes shorter in conversation. For example:

• आज प्लान तय करेंगे।
• आज प्लान फाइनल करेंगे।

The second one uses another common borrowed word:

• फाइनल करना = to finalize

So in real speech, people may mix Hindi and English quite freely. But हम आज प्लान तय करेंगे is a solid, correct, natural sentence to learn from.
