रिचार्ज सही है।

रिचार्ज is a borrowed word from English recharge. In everyday Hindi, it often means a mobile top-up, data/phone plan recharge, or the act/result of adding balance to a prepaid account.

So in this sentence, रिचार्ज is being used like a noun: the recharge / the top-up.

Hindi commonly puts the subject/topic first, then information about it, and often ends with the verb है.

So the structure is:

• रिचार्ज = subject/topic
• सही = correct / okay / valid / fine
• है = is

Literally, it is something like:

• The recharge is correct.

If you said सही रिचार्ज है, it would sound less natural for this meaning and could suggest something more like It is the correct recharge depending on context.

सही can mean several related things depending on context:

• correct
• right
• proper
• okay
• valid

In रिचार्ज सही है, it usually means that the recharge is correct, working, valid, or fine.

For example, someone may be checking whether the right plan was applied, and this sentence confirms that it is.

है is the present-tense form of the verb to be for he/she/it/this/that or singular non-human subjects in simple statements.

So:

• रिचार्ज सही है = The recharge is correct.

Without है, the sentence would sound incomplete in normal standard Hindi.

Some Hindi adjectives change form depending on gender and number, but सही is an indeclinable adjective in normal usage here. That means it stays the same.

Compare:

• लड़का अच्छा है = The boy is good.
• लड़की अच्छी है = The girl is good.

Here अच्छा / अच्छी changes.

But with सही:

• रिचार्ज सही है
• योजना सही है
• बात सही है

It stays सही.

Borrowed words can sometimes be treated as masculine in Hindi, but in this sentence, gender does not visibly matter because:

• सही does not change
• है also does not show gender in the present singular

So even if a learner is unsure about the gender of रिचार्ज, the sentence रिचार्ज सही है remains the same.

A simple learner-friendly pronunciation is:

• रिचार्ज = ri-chaarj
• सही = sa-hee
• है = often like hai

Put together:

• ri-chaarj sa-hee hai

A few notes:

• चा is a long chaa
• सही has two syllables: sa + hī
• है is usually pronounced somewhat like hai, not like English hay exactly, but close enough for beginners

It is very natural in everyday spoken Hindi, especially in contexts involving phones, mobile data, prepaid balance, online payments, and customer support.

Using English loanwords like रिचार्ज is extremely common in modern Hindi. So this sentence sounds normal and practical, not strange or overly formal.

Yes. Depending on context, सही है can be broader than just correct.

It might mean:

• The recharge is correct
• The recharge is fine
• The recharge went through properly
• The recharge is valid
• Everything is okay with the recharge

Hindi often relies on context more than English for this kind of sentence.

You add नहीं before है:

• रिचार्ज सही नहीं है।

This means:

• The recharge is not correct.
• The recharge is not okay.

This is a very common Hindi pattern:

• यह सही है = This is correct.
• यह सही नहीं है = This is not correct.

A very common way is to add क्या at the beginning:

• क्या रिचार्ज सही है?

This means:

• Is the recharge correct?
• Is the recharge okay?

In speech, intonation can also make it a question:

• रिचार्ज सही है?

That is common in conversation.

Yes, very often.

If the topic is already understood, someone can simply say:

• सही है।

Depending on tone and context, that can mean:

• It’s correct.
• It’s okay.
• That’s fine.
• Alright.

So in conversation, रिचार्ज सही है might be shortened to just सही है if everyone already knows you are talking about the recharge.
