थाली साफ है।

• थाली = plate / dish / platter
• साफ = clean
• है = is

So the structure is:

• थाली → the thing being talked about
• साफ → its condition
• है → the present-tense verb to be

Hindi often puts the main description before the verb है.

So:

• थाली = subject
• साफ = adjective/predicate
• है = final verb

A very common Hindi pattern is:

[subject] + [description] + है

Examples:

• कमरा बड़ा है। = The room is big.
• पानी ठंडा है। = The water is cold.

So थाली साफ है। follows a very normal Hindi sentence pattern.

है is the present singular form of the verb to be.

In this sentence, it works like English is:

• थाली साफ है। = The plate is clean.

You will see है with singular subjects very often:

• वह अच्छा है। = He/that is good.
• किताब नई है। = The book is new.

Its plural partner is usually हैं:

• थालियाँ साफ हैं। = The plates are clean.

Great question. In Hindi, not all adjectives change form.

There are two broad kinds of adjectives:

1. Declinable adjectives: they change according to gender/number
   Example:

   • अच्छा लड़का
   • अच्छी लड़की

2. Indeclinable adjectives: they stay the same
   Example:

   • साफ लड़का would sound odd semantically, but grammatically साफ itself does not change
   • साफ लड़की
   • साफ थाली

साफ belongs to the second type, so it stays साफ whether the noun is masculine, feminine, singular, or plural.

That is why it is:

• थाली साफ है not
• थाली साफी है or anything similar

थाली is a feminine noun.

A helpful pattern is that many Hindi nouns ending in -ी are feminine, though this is not a perfect rule. So थाली being feminine is something you learn as part of the word.

You can see its femininity more clearly when it appears with adjectives that do change:

• बड़ी थाली = big plate
• नई थाली = new plate

Here बड़ी and नई are feminine forms.

But with साफ, you do not see any visible feminine marking because साफ does not change.

A simple guide:

• था in थाली: the थ is an aspirated t sound, not the English th in think or this
• ली: like lee
• साफ: roughly saaf with a long aa
• है: usually like hai

A rough pronunciation in Latin letters:

• thaa-lee saaf hai

More carefully:

• थ = a puffed t
• ा = long aa
• ली = lee
• साफ = saaf
• है = hai

So: thaa-lee saaf hai

No. This is a very common confusion.

Hindi थ is not the English th sound from think or this.

Instead, थ is:

• a t sound
• made with aspiration, meaning a little burst of air after it

So:

• त = unaspirated t
• थ = aspirated t

A good trick: say a t and release a noticeable puff of air.

Both spellings are commonly seen.

• साफ
• साफ़

The version with the dot, फ़, shows that the consonant is pronounced closer to f. Without the dot, many people still pronounce it as f anyway in modern Hindi.

So in real life:

• साफ and साफ़ usually mean the same thing
• both are accepted in common usage

Learners will often see both spellings in books, signs, and online writing.

No. Hindi does not normally use articles the way English does.

So थाली साफ है। could mean:

• The plate is clean
• A plate is clean
• The dish is clean

Which one sounds best depends on context.

Hindi often leaves that information unspoken unless it needs to be made specific in some other way.

Yes. थाली can refer to a plate, dish, or platter, often a somewhat larger serving plate. In many contexts, it can also suggest a metal plate or a meal platter.

So the exact English word may vary by context:

• plate
• dish
• platter

In everyday beginner translation, plate is usually the safest choice.

In very casual speech or in headlines, people sometimes drop forms of to be, but for standard beginner Hindi, you should keep है.

So the normal full sentence is:

• थाली साफ है।

If you omit है, it may sound incomplete in careful standard speech.

As a learner, it is best to include है until you become familiar with when native speakers naturally leave it out.

Put नहीं before है:

• थाली साफ नहीं है। = The plate is not clean.

This is a very common Hindi pattern:

• वह यहाँ नहीं है। = He/She is not here.
• कमरा बड़ा नहीं है। = The room is not big.

So the pattern is:

[subject] + [description] + नहीं + है

A simple yes/no question is:

• क्या थाली साफ है? = Is the plate clean?

Here क्या at the beginning marks the sentence as a yes/no question.

In speech, intonation can also help, but for learners the safest pattern is:

क्या + [statement]?

So:

• क्या पानी ठंडा है?
• क्या कमरा खाली है?
• क्या थाली साफ है?

If you mean plates, the noun and verb change like this:

• थालियाँ साफ हैं। = The plates are clean.

Changes:

• थाली → थालियाँ = plate → plates
• है → हैं = is → are

Notice that साफ still does not change, because it is an indeclinable adjective.

Yes. It is simple, correct, and completely natural.

Hindi speakers often use exactly this kind of sentence to describe the state of an object:

• कपड़ा गीला है। = The cloth is wet.
• गिलास खाली है। = The glass is empty.
• थाली साफ है। = The plate is clean.

It is a very useful beginner pattern to learn well.
