हर कदम ज़रूरी है।

हर means every or each.

So हर कदम means every step.

A useful thing to remember is that हर usually stays the same and does not change for gender or number:

• हर आदमी = every man
• हर औरत = every woman
• हर दिन = every day

कदम means step.

In this sentence, हर कदम is best understood as every step in a literal or figurative sense.

It can be used:

• literally: a physical step while walking
• figuratively: a stage, action, or move in a process

So the sentence can sound practical, motivational, or philosophical depending on context.

Hindi often puts things in the order subject/topic + description + linking verb.

So:

• हर कदम = every step
• ज़रूरी = necessary/important
• है = is

Literally, the structure is: Every step necessary is.

That is normal in Hindi. The verb है usually comes at the end.

ज़रूरी most often means necessary, required, or important depending on context.

In this sentence, it could be translated as:

• Every step is necessary
• Every step is important

Both are natural, and the best choice depends on the situation.

Examples:

• यह बहुत ज़रूरी है। = This is very necessary / This is very important.
• मुझे एक ज़रूरी काम है। = I have an important/urgent task.

Because हर कदम is treated as grammatically singular in Hindi.

Even though every step refers to many individual steps in meaning, Hindi uses हर with a singular noun:

• हर कदम ज़रूरी है।
• हर आदमी तैयार है।
• हर किताब अच्छी है।

So the verb agrees as singular: है, not हैं.

No, ज़रूरी does not change here.

Some Hindi adjectives change form depending on gender and number, but others do not. ज़रूरी is one of the adjectives that usually stays the same:

• कदम ज़रूरी है
• बात ज़रूरी है
• किताबें ज़रूरी हैं

What changes is usually the verb, not ज़रूरी itself.

कदम is generally masculine.

That helps explain why, if you replace it with a pronoun, you might use masculine agreement in some contexts.

But in this sentence, the adjective ज़रूरी does not show gender anyway, so you do not see a masculine form change.

Sometimes, especially in casual speech, people may drop है, particularly in headlines, slogans, notes, or very informal style:

• हर कदम ज़रूरी।

But in full, standard Hindi, हर कदम ज़रूरी है। is the normal sentence.

For learners, it is best to include है unless you have a specific reason not to.

ज़रूरी is pronounced roughly like za-roo-ree.

The letter ज़ is ज with a dot, and it represents a z sound, which came into Hindi through Persian/Arabic influence.

So:

• ज sounds like j in jam
• ज़ sounds like z in zoo

Many speakers may pronounce ज़रूरी close to जरूरी, but the spelling ज़रूरी shows the borrowed z sound.

It sounds natural.

हर कदम ज़रूरी है। is a very normal Hindi sentence and could easily appear in:

• motivational speech
• education
• health campaigns
• advice
• emotional or reflective writing

It has a broad, natural feel similar to English expressions like:

• Every step matters
• Every step is important
• Every step is necessary

Yes, हर एक कदम ज़रूरी है is also possible.

It means almost the same thing, but हर एक adds a little extra emphasis, like:

• each and every step
• every single step

Compare:

• हर कदम ज़रूरी है। = Every step is necessary.
• हर एक कदम ज़रूरी है। = Each and every step is necessary.

This sentence is a very useful pattern:

हर + noun + adjective + है

Examples:

• हर दिन नया है। = Every day is new.
• हर सवाल महत्वपूर्ण है। = Every question is important.
• हर मौका खास है। = Every opportunity is special.

You can also change the noun:

• हर पल ज़रूरी है। = Every moment is important.
• हर फैसला ज़रूरी है। = Every decision is important.

This makes हर कदम ज़रूरी है। a great model sentence for building your own Hindi.
