वह आदमी ठग है।

वह can mean he, she, or that, depending on context.

In वह आदमी ठग है, because वह is directly before the noun आदमी (man), it most naturally means that:

• वह आदमी = that man

If वह stood alone, it could mean he or she:

• वह ठग है = He/She is a swindler

In everyday speech, वह is often pronounced more like वो.

Hindi does not normally use articles like a, an, and the the way English does.

So:

• आदमी can mean a man, the man, or just man, depending on context.
• ठग can mean a swindler or the swindler, depending on context.

That means वह आदमी ठग है naturally translates as:

• That man is a swindler
• or, depending on the context, That man is the swindler

If you want to emphasize one/a, Hindi can use एक, but it is not necessary here.

Hindi usually puts the verb at the end of the sentence.

So the structure here is:

• वह आदमी = subject
• ठग = predicate noun
• है = is

A very literal word-for-word order would be:

• That man swindler is

This is completely normal in Hindi. The verb है usually comes at the end.

है is the present-tense form of होना, which means to be.

So here it means is.

In this sentence:

• वह आदमी ठग है = That man is a swindler

You can think of है as linking the subject and the description, just like is in English.

Not exactly.

Although English thug historically comes from the same source, modern Hindi ठग usually means:

• swindler
• con artist
• cheat
• fraudster

So in modern Hindi, ठग is usually about deception, not necessarily violent crime.

That is an important difference for English speakers, because thug in modern English often suggests a violent criminal, while ठग in Hindi often suggests someone who tricks people.

A simple learner-friendly pronunciation is:

• vah aadmi thag hai

A more natural everyday pronunciation is often closer to:

• voh aadmi thag hai

A few notes:

• वह is often spoken as वो / voh
• आदमी = aadmi
  
  • the first आ is a long aa
• ठग starts with ठ, which is a retroflex aspirated sound
  
  • it is not the same as English t
• है is pronounced roughly like heh or hai, depending on how narrowly you describe it

If you are just starting out, voh aadmi thag hai is a good practical approximation.

आदमी often means man, but in some contexts it can also mean person or human being.

In this sentence, because of the translation and the context, it means man:

• वह आदमी = that man

In everyday Hindi, आदमी is very common and natural. It is less formal than some other words such as पुरुष.

Here ठग is a noun used as a predicate noun, and it stays the same.

Hindi does not always change predicate nouns to match the subject the way learners might expect.

So:

• वह आदमी ठग है = That man is a swindler
• वह औरत ठग है = That woman is a swindler

In both cases, ठग can stay the same.

This is different from some adjectives in Hindi, which may change form depending on gender and number.

Not as naturally as वह ठग है.

Because this sentence includes आदमी, it specifically says that man:

• वह आदमी ठग है = That man is a swindler

If you want simply He is a swindler, the more natural sentence is:

• वह ठग है

So adding आदमी makes the reference more explicit.

Because this is a very simple equational sentence: one thing is being identified as another.

Structure:

• subject: वह आदमी
• predicate noun: ठग
• verb: है

There is no direct object here, so को is not needed.
There is no perfective transitive construction here, so ने is not needed either.

This is one of the simplest Hindi sentence patterns.

Yes, it is fairly strong.

Calling someone ठग means you are saying that person is a cheat, fraud, or con artist. That is a serious accusation, not a mild description.

So although the grammar is simple, the meaning is quite strong. Use it carefully.

है is made of:

• ह
• plus the vowel sign ै

That vowel sign represents the ai/ɛ-type vowel sound.

So:

• ह = ha
• है = hai / hɛ

This is very common in Hindi, where consonants combine with vowel marks instead of writing every vowel as a separate full letter.
