माँ आज खुश है।

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

In माँ आज खुश है:

• माँ = mother
• आज = today
• खुश = happy
• है = is

So Hindi says something like Mother today happy is.

This is normal Hindi word order.

है is the present-tense form of the verb to be for he/she/it/this/that and also for singular nouns.

In this sentence, it means is.

So खुश है means is happy.

Good question. Many Hindi adjectives do change for gender and number, but some do not. खुश is one of the adjectives that usually stays the same.

So:

• माँ खुश है = Mother is happy
• पिता खुश हैं = Father is happy
• लड़की खुश है = The girl is happy
• लड़के खुश हैं = The boys are happy

The adjective खुश stays खुश.

माँ is the standard spelling, with the ँ sign indicating nasalization.

It is pronounced roughly like maa with a nasal sound. In everyday typing, you may sometimes see मां, but माँ is generally considered the more correct standard spelling.

A simple pronunciation guide is:

mā̃ āj khush hai

Roughly:

• माँ = maa with a nasal sound
• आज = aaj
• खुश = khush (the kh is an aspirated sound, not like English k alone)
• है = often sounds like hai

A natural rhythm would be: maa(n) aaj khush hai

Hindi does not use articles the same way English does. There is no direct equivalent of the or a/an in many ordinary sentences.

So माँ can mean:

• mother
• the mother
• my mother, depending on context

In this sentence, context usually makes it clear that it means Mother/Mom.

Yes, Hindi allows some flexibility, especially with time words like आज.

These can all work, depending on emphasis:

• माँ आज खुश है।
• आज माँ खुश है।

Both mean essentially the same thing: Mother is happy today.

The first one is very natural. The second puts a little more focus on today.

In Hindi, family words are often used without a possessive when the relationship is obvious from context.

So:

• माँ खुश है can naturally mean Mom is happy
• You do not always need मेरी माँ = my mother

If you want to be more explicit, you can say:

• मेरी माँ आज खुश है। = My mother is happy today.

Normally, with singular माँ, you use है:

• माँ खुश है।

But sometimes speakers use plural/respectful forms for honor or politeness with family members or respected people. In that case, you may hear:

• माँ खुश हैं।

So:

• है = grammatically singular and very normal
• हैं = respectful usage, also common in some contexts

Both can be heard, depending on style and family speech habits.

It is complete. In Hindi, an adjective plus to be can form a full sentence.

So खुश है literally means is happy, and that is enough.

Hindi does not need an extra word like feeling here.
You do not need:

• माँ आज खुश महसूस कर रही है for this simple idea

That longer version is possible, but माँ आज खुश है is the natural simple sentence.

आज is an adverb of time. It tells you when something is true.

Here it modifies the whole statement:

• माँ ... खुश है = Mother is happy
• आज = today

So it means that her happiness is true today.

Yes. खुश can often be translated as happy, glad, or pleased, depending on context.

So possible English renderings include:

• Mom is happy today.
• Mother is happy today.
• Mom is glad today.

The exact best translation depends on tone and situation.

Then the verb would usually change to हैं.

For example:

• माएँ आज खुश हैं। = Mothers are happy today.
• बच्चे आज खुश हैं। = The children are happy today.

Notice that खुश still stays the same, but है becomes हैं for plural subjects.
