शब्दकोश उपलब्ध है।

Hindi usually follows Subject–Object/Complement–Verb word order, so the verb often comes last.

So:

• शब्दकोश = the subject
• उपलब्ध = a descriptive word, meaning available
• है = is

A very literal English-style breakdown would be:

• Dictionary available is.

But natural English is:

• The dictionary is available.

This verb-final pattern is one of the most important word-order differences between Hindi and English.

In this sentence, उपलब्ध is best understood as an adjective meaning available.

The actual verb is है = is.

So the structure is similar to:

• कमरा साफ़ है। = The room is clean.
• शब्दकोश उपलब्ध है। = The dictionary is available.

In both cases, the descriptive word (साफ़, उपलब्ध) is not the main verb; the verb is है.

Hindi does not have articles like English a, an, and the in the same way.

So शब्दकोश can mean:

• dictionary
• a dictionary
• the dictionary

Which one is intended depends on context.

That means शब्दकोश उपलब्ध है। could be understood as:

• The dictionary is available.
• A dictionary is available.

If the meaning has already been shown to the learner, the context tells you which reading is intended.

शब्दकोश is generally treated as masculine.

In this particular sentence, that does not create a visible change in उपलब्ध, because उपलब्ध often stays the same in this kind of usage.

However, gender matters in Hindi because many adjectives and verbs can agree with the noun.

For example, with a different adjective you might clearly see agreement:

• कमरा बड़ा है। = The room is big.
• किताब बड़ी है। = The book is big.

Here, बड़ा / बड़ी changes with gender.

With उपलब्ध, that change is not usually visible in the same way.

Yes. शब्दकोश is a standard Hindi word for dictionary.

It can refer to:

• a physical dictionary
• a bilingual dictionary
• sometimes a lexical reference more generally

In everyday speech, people may also use the English loanword डिक्शनरी.

So you may hear both:

• शब्दकोश उपलब्ध है।
• डिक्शनरी उपलब्ध है।

The first is more formal or standard Hindi; the second is very common in casual modern usage.

A rough pronunciation guide is:

• शब्दकोश ≈ shabd-kosh
• उपलब्ध ≈ upalabdh
• है ≈ hai

A few notes:

• In शब्दकोश, the cluster ब्द can feel difficult for English speakers. It is something like shabd.
• In उपलब्ध, the ending ब्ध is also a consonant cluster and may be pronounced more smoothly or lightly in natural speech than it looks in writing.
• है sounds like hai, somewhat like high, but shorter and lighter.

A careful learner pronunciation might be:

• shabd-kosh upa-labdh hai

Hindi often leaves out words that are not necessary from context.

English often prefers something explicit, such as:

• It is available.
• This dictionary is available.

But Hindi can be more compact:

• शब्दकोश उपलब्ध है।

If the dictionary is already known from context, Hindi does not need an extra pronoun.

If you want to be more specific, you could say:

• यह शब्दकोश उपलब्ध है। = This dictionary is available.
• वह शब्दकोश उपलब्ध है। = That dictionary is available.

Yes. Because Hindi usually does not mark a/the, the sentence can mean either one depending on context.

So:

• शब्दकोश उपलब्ध है।

may be interpreted as:

• A dictionary is available.
• The dictionary is available.

If you want to make one more explicit, Hindi sometimes uses एक:

• एक शब्दकोश उपलब्ध है। = A dictionary is available.

But एक is not always required.

To make it negative, add नहीं before है:

• शब्दकोश उपलब्ध नहीं है। = The dictionary is not available.

This is a very common Hindi pattern:

• कमरा साफ़ है। = The room is clean.
• कमरा साफ़ नहीं है। = The room is not clean.

So with predicate adjectives, नहीं usually comes before the form of to be.

A common yes/no question version is:

• क्या शब्दकोश उपलब्ध है?

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

The rest of the sentence stays the same:

• शब्दकोश उपलब्ध है। = statement
• क्या शब्दकोश उपलब्ध है? = Is the dictionary available?

In speech, intonation also helps show that it is a question.

The plural would usually be:

• शब्दकोश उपलब्ध हैं। = The dictionaries are available.

The main change is:

• है = is
• हैं = are

In many contexts, शब्दकोश itself may stay the same in form, and the verb tells you whether the subject is singular or plural.

So compare:

• शब्दकोश उपलब्ध है। = The dictionary is available.
• शब्दकोश उपलब्ध हैं। = The dictionaries are available.

It sounds neutral to somewhat formal because of the word उपलब्ध.

You would often see this in:

• notices
• websites
• libraries
• catalogs
• customer-service contexts

In everyday casual speech, people might say something simpler depending on context, but उपलब्ध है is very common and completely natural.

For example, on a website or in an office, उपलब्ध है is exactly the kind of wording you would expect.

Yes: the most important thing is that Hindi often says noun + adjective + is, whereas English says noun + is + adjective.

So:

• Hindi: शब्दकोश उपलब्ध है
• Literal order: dictionary available is
• Natural English: The dictionary is available

This is a very common pattern in Hindi, so getting comfortable with it will help a lot.
