मेहनत ज़रूरी है।

A natural pronunciation is:

mehnat zarūrī hai

A rough guide:

• मेहनत = MEH-hnut / MEH-nut
• ज़रूरी = za-ROO-ree
• है = hai, often sounding a bit like heh or hai depending on accent and speed

A few notes:

• मेह in मेहनत has the vowel e as in met, but slightly longer/smoother.
• ज़ is like the English z sound.
• रूरी has a long ū sound, like oo in food.
• In normal speech, है is often light and unstressed.

The sentence breaks down like this:

• मेहनत = hard work, effort, मेहनत as a noun
• ज़रूरी = necessary, important, essential
• है = is

So structurally, it is:

• मेहनत = subject/topic
• ज़रूरी = predicate adjective
• है = the verb is

Because मेहनत is a noun meaning hard work or effort.

So मेहनत ज़रूरी है literally works like:

• Hard work is necessary
• Effort is necessary

If you wanted to say to work hard is necessary, Hindi often uses:

• मेहनत करना ज़रूरी है = Working hard is necessary

So:

• मेहनत ज़रूरी है focuses on hard work/effort as a thing or concept
• मेहनत करना ज़रूरी है focuses on the act of working hard

Both are natural, but the version without करना is shorter and more general.

In this sentence, ज़रूरी is not directly describing the noun inside a noun phrase. It is part of the predicate.

Hindi structure here is:

• मेहनत
  • ज़रूरी
    • है
• literally: Hard work necessary is

This is very normal in Hindi. Predicate adjectives usually come before है:

• यह अच्छा है = This is good
• पानी ठंडा है = The water is cold
• मेहनत ज़रूरी है = Hard work is necessary

So ज़रूरी is not being used like necessary hard work. It is being used like is necessary.

है is the present-tense form of to be for singular subjects in simple statements.

Here it means is.

So:

• मेहनत ज़रूरी है = Hard work is necessary

Compare:

• मैं खुश हूँ = I am happy
• वह तैयार है = He/she is ready
• यह सही है = This is correct

Without है, the sentence would sound incomplete in standard Hindi, though in casual speech or headlines it may sometimes be omitted.

Yes, it is a general idea, but in Hindi मेहनत is treated as a singular noun here.

So Hindi uses singular है, not plural हैं.

This is similar to English mass or abstract nouns:

• Patience is important
• Exercise is useful
• Hard work is necessary

In Hindi:

• सब्र ज़रूरी है
• व्यायाम अच्छा है
• मेहनत ज़रूरी है

Yes, मेहनत is feminine.

You can see that in other contexts, for example:

• बहुत मेहनत हुई
• मेरी मेहनत

But ज़रूरी does not change here because it is an indeclinable adjective in modern Hindi usage. That means it usually stays the same regardless of gender or number.

Compare with a changing adjective:

• लड़का अच्छा है
• लड़की अच्छी है

But with ज़रूरी:

• काम ज़रूरी है
• बात ज़रूरी है
• चीज़ें ज़रूरी हैं

The adjective stays ज़रूरी.

Only the verb can change for number:

• बात ज़रूरी है
• बातें ज़रूरी हैं

That dot is called a nukta.

It changes the sound of the letter.

• ज is usually pronounced like j in jam
• ज़ is pronounced like z in zoo

So:

• जरूरी is often written in everyday Hindi
• ज़रूरी is the more precise spelling for the z sound

In modern writing, both spellings are very common, and many native speakers do not consistently write the nukta. But pronunciation-wise, ज़रूरी is the standard form.

Not originally. ज़रूरी came into Hindi through Persian/Urdu usage, ultimately from Arabic roots.

This is very common in Hindi vocabulary. Hindi uses words from several sources:

• Sanskrit-derived words
• Prakrit/Apabhraṃśa developments
• Persian and Arabic borrowings
• English borrowings

So ज़रूरी is extremely common and natural in everyday Hindi.

A more Sanskrit-style alternative would be:

• आवश्यक = necessary
• मेहनत आवश्यक है

But in everyday speech, ज़रूरी is usually more common and more conversational.

Yes, absolutely.

Compare:

• मेहनत ज़रूरी है = Hard work is necessary / Effort is necessary
• मेहनत करना ज़रूरी है = It is necessary to work hard / Working hard is necessary

The difference is small but useful:

• मेहनत ज़रूरी है sounds more general and abstract
• मेहनत करना ज़रूरी है emphasizes the action

For example:

• सफलता के लिए मेहनत ज़रूरी है = Hard work is necessary for success
• अगर पास होना है, तो मेहनत करना ज़रूरी है = If you want to pass, then it is necessary to work hard

Yes, that is the literal word order, and it can help you understand the grammar:

• मेहनत = hard work
• ज़रूरी = necessary
• है = is

So the literal structure is:

• Hard work necessary is

But natural English reorders it as:

• Hard work is necessary

This is a very common difference between Hindi and English. Hindi often places the main descriptive word before the final verb.

In full, standard sentences, है is normally included:

• मेहनत ज़रूरी है

But it may be omitted in:

• headlines
• slogans
• notes
• very casual spoken style
• poetry

For example, a slogan might say:

• सफलता के लिए मेहनत ज़रूरी

But for normal learning and correct standard usage, you should use:

• मेहनत ज़रूरी है

Yes. Some common alternatives are:

• मेहनत ज़रूरी है। = Hard work is necessary.
• मेहनत करना ज़रूरी है। = It is necessary to work hard.
• कड़ी मेहनत ज़रूरी है। = Hard work / intense effort is necessary.
• सफलता के लिए मेहनत ज़रूरी है। = Hard work is necessary for success.
• बिना मेहनत के सफलता नहीं मिलती। = Without hard work, success does not come.

These all express related ideas, but मेहनत ज़रूरी है is one of the most simple and natural ways to say it.
