पैंट रंगीन है।

In Hindi, पैंट usually refers to one garment / one pair of trousers and is treated as a singular noun.

So:

• पैंट रंगीन है। = one pair of pants is colorful
• पैंटें रंगीन हैं। = multiple pairs of pants are colorful

This is a common difference between English and Hindi: the English word pants is grammatically plural, but Hindi पैंट is usually singular.

पैंट is usually feminine in standard Hindi.

That is why you would say things like:

• मेरी पैंट = my pants
• नई पैंट = new pants

You generally just have to learn the gender of borrowed nouns like this, because it is not always predictable from the form alone.

Because in this sentence, रंगीन is being used as a predicate adjective with है.

Hindi often follows this pattern:

noun + adjective + है

So:

• पैंट रंगीन है। literally: The pants colorful is

But if the adjective comes directly before the noun, it works more like colorful pants:

• रंगीन पैंट = colorful pants

So the difference is:

• रंगीन पैंट = colorful pants
• पैंट रंगीन है = the pants are colorful

Because रंगीन is an indeclinable adjective in normal use. That means it usually stays the same no matter what noun it describes.

Examples:

• रंगीन लड़का
• रंगीन लड़की
• रंगीन कपड़े
• पैंट रंगीन है

Compare that with an adjective like अच्छा, which does change:

• अच्छा लड़का
• अच्छी लड़की
• अच्छे लड़के

So रंगीन stays रंगीन, but adjectives like अच्छा change form.

Here, रंगीन means something like:

• colorful
• brightly colored
• having color

In everyday clothing contexts, it often suggests that something is not plain or dull, and may have strong or multiple colors.

Depending on context, it can sometimes be translated as colored rather than colorful, but colorful is usually the most natural learning gloss here.

Because Hindi usually puts the main verb, or the to be form, near the end of the sentence.

So the structure is:

subject + description + है

In this case:

• पैंट = subject
• रंगीन = description
• है = is

This is very normal Hindi word order.

Hindi usually does not use articles the way English does.

So पैंट रंगीन है। can mean:

• The pants are colorful
• A pair of pants is colorful
• These pants are colorful

The exact meaning depends on context.

If you want to be more specific, Hindi often uses words like:

• यह पैंट = this pair of pants
• वह पैंट = that pair of pants

A simple learner-friendly pronunciation is:

paint rang-een hai

A slightly more accurate guide:

• पैंट = roughly pẽṭ or paiṇṭ
• रंगीन = rang-een
• है = hai

A few notes:

• ट is a retroflex t, made with the tongue curled back slightly
• -ीन in रंगीन has a long ee sound
• है is pronounced like hai, not like English hay

Yes, exactly the same pattern.

For example:

• पैंट काली है। = The pants are black.
• पैंट नई है। = The pants are new.
• पैंट महंगी है। = The pants are expensive.

Notice that some adjectives, like काली and नई, do change form to match the feminine noun पैंट. But रंगीन does not change.

Not by itself in most contexts.

• रंगीन पैंट is a noun phrase meaning colorful pants
• पैंट रंगीन है is a full sentence meaning The pants are colorful

So:

• यह रंगीन पैंट है। = This is colorful pants / This is a colorful pair of pants.
• पैंट रंगीन है। = The pants are colorful.

So yes, रंगीन पैंट is correct, but it does a different job in the sentence.
