सीढ़ियाँ ऊपर जाती हैं।

सीढ़ियाँ is the plural form of सीढ़ी.

• सीढ़ी = a stair / a staircase / a ladder, depending on context
• सीढ़ियाँ = stairs

In this sentence, सीढ़ियाँ means the stairs. Hindi often uses the plural form when English also says stairs.

Also, सीढ़ी is a feminine noun, and that matters because the verb agrees with it.

Because सीढ़ियाँ is feminine plural.

In Hindi, with this kind of sentence, the verb agrees with the subject:

• masculine singular: जाता है
• feminine singular: जाती है
• masculine plural: जाते हैं
• feminine plural: जाती हैं

Since सीढ़ियाँ is feminine plural, the correct form is जाती हैं.

Yes. जाती हैं comes from जाना, which usually means to go.

Here is the breakdown:

• जा- = the verb root
• -ती = feminine habitual participle ending
• हैं = present-tense auxiliary used with plural/respectful subjects

So जाती हैं is the feminine plural habitual/present form: go, lead, or go up, depending on context.

In this sentence, Hindi uses go in a way English often translates as lead:

• सीढ़ियाँ ऊपर जाती हैं = The stairs go up / lead upstairs

ऊपर means up, above, or upstairs, depending on context.

In this sentence, it works like an adverb showing direction:

• सीढ़ियाँ ऊपर जाती हैं = The stairs go up

So ऊपर tells you where the stairs go.

This is a very normal Hindi way to express the idea.

Hindi often uses जाना (to go) for things like roads, stairs, paths, and routes:

• यह सड़क दिल्ली जाती है। = This road goes to Delhi.
• सीढ़ियाँ ऊपर जाती हैं। = The stairs go up.

In natural English, you might also say:

• The stairs lead upstairs
• The stairs go up
• These stairs go up

So the Hindi is completely normal; it just maps a little differently onto English.

This is the habitual/present general form.

It describes a general fact, not an action happening right now in time:

• सीढ़ियाँ ऊपर जाती हैं। = The stairs go up.

It is not saying the stairs are currently moving. It is describing their usual direction or function.

That is why Hindi uses जाती हैं, not something like a progressive form.

Grammatically, that form exists, but it would usually sound wrong or unnatural here.

• जा रही हैं is a progressive form: are going
• That suggests something is actively in progress right now

Since stairs are not literally moving, सीढ़ियाँ ऊपर जा रही हैं would sound strange in most contexts.

For a general description, जाती हैं is the natural choice.

हैं is the auxiliary verb used with a plural subject (or with respectful singular).

Since सीढ़ियाँ is plural, Hindi uses हैं rather than है.

Compare:

• सीढ़ी ऊपर जाती है। = The stair/staircase goes up.
• सीढ़ियाँ ऊपर जाती हैं। = The stairs go up.

So हैं helps mark the sentence as plural.

Yes, depending on context.

Hindi often uses:

• सीढ़ी for a stair, a staircase, or sometimes even a ladder
• सीढ़ियाँ for stairs

In real usage, context tells you what is meant. In this sentence, सीढ़ियाँ clearly refers to stairs or a flight of stairs.

The order here is very natural:

• सीढ़ियाँ = subject
• ऊपर = direction/adverb
• जाती हैं = verb phrase

So the pattern is roughly:

subject + direction/adverb + verb

Hindi word order is flexible, so other orders are possible for emphasis, but सीढ़ियाँ ऊपर जाती हैं is the most straightforward neutral version.

Roughly: see-rhee-yaan

A few useful points:

• सी sounds like see
• ढ़ी has a retroflex/flapped sound that English does not really have
• याँ gives a yaã sound, with nasalization

So the ending is not just yaa; it is slightly nasal: yaã.

Learners often type it as सीढ़ियां, but the standard spelling is सीढ़ियाँ.

Because many feminine nouns ending in -ी form the direct plural with -याँ.

For example:

• लड़की → लड़कियाँ
• कुर्सी → कुर्सियाँ
• सीढ़ी → सीढ़ियाँ

So:

• singular: सीढ़ी
• plural: सीढ़ियाँ

This is a very common pattern in Hindi.

Those are possible in certain contexts, but they are not the most basic version.

• सीढ़ियाँ ऊपर जाती हैं = simple and natural: The stairs go up
• सीढ़ियाँ ऊपर तक जाती हैं = The stairs go all the way up
• ऊपर को is less common/natural here in standard everyday Hindi

So for a basic sentence, सीढ़ियाँ ऊपर जाती हैं is the best form to learn first.
