लिफ्ट नहीं है, लेकिन सीढ़ियाँ साफ हैं।

In Hindi, negation usually comes before the verb. So:

• लिफ्ट है = There is a lift.
• लिफ्ट नहीं है = There is no lift / The lift is not there.

This is very common with forms of होना (to be):

• पानी है = There is water.
• पानी नहीं है = There is no water.

So नहीं is simply negating है.

Because the subjects are different:

• लिफ्ट is being treated as singular, so Hindi uses है.
• सीढ़ियाँ means stairs, which is plural, so Hindi uses हैं.

So:

• लिफ्ट नहीं है = The lift is not there.
• सीढ़ियाँ साफ हैं = The stairs are clean.

A quick comparison:

• कमरा साफ है = The room is clean.
• कमरे साफ हैं = The rooms are clean.

In Hindi, सीढ़ियाँ is the normal plural form meaning stairs/steps. It is grammatically plural, so it takes plural agreement:

• सीढ़ियाँ साफ हैं = The stairs are clean.

The singular form is सीढ़ी, which usually means a step or a stair, and in some contexts can also mean a ladder.

Examples:

• एक सीढ़ी = one step / one stair
• सीढ़ियाँ = stairs

So even if English sometimes treats stairs as a single unit, Hindi grammar here treats सीढ़ियाँ as plural.

Good question. Some Hindi adjectives change form depending on gender and number, but others are indeclinable and stay the same.

साफ is one of those adjectives that usually does not change. So you can say:

• कमरा साफ है = The room is clean.
• मेज़ साफ है = The table is clean.
• सीढ़ियाँ साफ हैं = The stairs are clean.

Compare this with a changing adjective like अच्छा:

• अच्छा कमरा
• अच्छी मेज़
• अच्छे कमरे

But साफ stays साफ.

लेकिन means but. It connects two contrasting ideas:

• लिफ्ट नहीं है = There is no lift
• लेकिन = but
• सीढ़ियाँ साफ हैं = the stairs are clean

So the whole sentence means:

• There is no lift, but the stairs are clean.

You can often place लेकिन between two full clauses, just like but in English.

Example:

• कमरा छोटा है, लेकिन साफ है। = The room is small, but clean.

Hindi usually does not use articles like a, an, or the the way English does.

So:

• लिफ्ट नहीं है can mean There is no lift or The lift is not there, depending on context.
• सीढ़ियाँ साफ हैं can mean The stairs are clean or simply Stairs are clean, though in natural English we would usually say the stairs.

Hindi often leaves this to context rather than marking it with a separate word.

लिफ्ट is a borrowing from English lift. Hindi uses many English loanwords, especially for modern objects and building-related vocabulary.

Depending on region and context, you may also hear:

• लिफ्ट = lift/elevator
• एलेवेटर = elevator

But लिफ्ट is very common and natural in everyday Hindi.

Hindi nouns do not always show gender clearly from their spelling, especially borrowed words. लिफ्ट is commonly treated as feminine.

You can tell in other sentences where adjectives or verbs show agreement more clearly, for example:

• नई लिफ्ट = new lift
  Here नई shows feminine agreement.

In your sentence, you do not directly see feminine marking on साफ, because साफ does not change, and है is used for both masculine and feminine singular. So the gender is not very visible here.

The basic pattern is:

• subject + adjective/complement + verb

So:

• सीढ़ियाँ = stairs
• साफ = clean
• हैं = are

Literally: Stairs clean are.

This is a very common Hindi structure with to be:

• घर बड़ा है = The house is big.
• किताब नई है = The book is new.
• सीढ़ियाँ साफ हैं = The stairs are clean.

The ending याँ in सीढ़ियाँ marks a common feminine plural oblique/direct-type pattern you will see in many nouns. The nasalization is part of the normal plural form.

Singular and plural:

• सीढ़ी = stair / step
• सीढ़ियाँ = stairs

Other similar feminine nouns:

• कुर्सी → कुर्सियाँ = chair → chairs
• चिड़िया → चिड़ियाँ = bird → birds

So the nasalized ending is a clue that the noun is plural.

Yes. The given sentence is perfectly natural, but Hindi offers other ways too, depending on tone and context. For example:

• लिफ्ट नहीं है, पर सीढ़ियाँ साफ हैं।

  • पर is another common word for but.

• यहाँ लिफ्ट नहीं है, लेकिन सीढ़ियाँ साफ हैं।

  • यहाँ = here
  • This makes the location more explicit: There is no lift here, but the stairs are clean.

• लिफ्ट तो नहीं है, लेकिन सीढ़ियाँ साफ हैं।

  • तो can add emphasis or contrast.

The original sentence is simple, clear, and very natural.

A rough pronunciation guide is:

• लिफ्ट नहीं है, लेकिन सीढ़ियाँ साफ हैं।
• lift nahin hai, lekin seedhiyan saaf hain

A few notes:

• नहीं = nahin or nahī̃
  The ending is nasalized.
• सीढ़ियाँ = seedhiyan
  The ढ़ is a retroflex sound, and the ending is nasalized.
• हैं = hain
  Also nasalized.

If you say it slowly and clearly as:

lift nahin hai, lekin seedhiyan saaf hain

you will be understood well.
