टीका पिल्ले के लिए है।

A natural breakdown is:

• टीका = vaccine, shot, or injection in this context
• पिल्ले = puppy
• के लिए = for
• है = is

So the structure is literally something like:

vaccine puppy-for is

which becomes natural English as The vaccine is for the puppy.

Because पिल्ला is the basic dictionary form, but after a postposition like के लिए, Hindi uses the oblique form.

For many masculine nouns ending in -ा, the singular oblique changes to -े:

• पिल्ला → पिल्ले
• लड़का → लड़के
• कुत्ता → कुत्ते

So:

• पिल्ला = puppy
• पिल्ले के लिए = for the puppy

This is one of the most important noun patterns in Hindi.

के लिए means for, meant for, or intended for.

In this sentence, it shows who the vaccine is meant for:

• पिल्ले के लिए = for the puppy

It is best to learn के लिए as a fixed chunk meaning for rather than trying to translate each part separately every time.

Because Hindi normally puts the verb at the end.

English: The vaccine is for the puppy.
Hindi: टीका पिल्ले के लिए है।

That final है is the verb is, and its position at the end is completely normal in Hindi.

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

So टीका can mean:

• a vaccine
• the vaccine

and the exact meaning depends on context.

That is why टीका पिल्ले के लिए है। can still naturally mean The vaccine is for the puppy even though there is no separate word for the.

टीका is masculine.

In this sentence, that does not change much on the surface, because है is the same for masculine and feminine singular subjects in the present tense.

But gender can matter with adjectives and some other forms. For example:

• अच्छा टीका = good vaccine
• अच्छी दवा = good medicine

So yes, टीका has gender, but this particular sentence does not highlight it very strongly.

Yes. टीका can have several meanings depending on context, including:

• vaccine / shot
• tilak / mark on the forehead
• commentary / annotation

In your sentence, the meaning is clearly vaccine because of the context.

This is very common in Hindi: one word may have several meanings, and context tells you which one is intended.

A simple pronunciation guide is:

ṭīkā pille ke liye hai

A rough English-style approximation:

TEE-kaa PIL-lay kay LI-yeh hai

A few notes:

• टी sounds like tee
• का sounds like kaa
• पिल्ले has a doubled l sound: pil-le
• लिए is usually pronounced roughly li-ye
• है is pronounced hai, somewhat like high

You would say:

टीका पिल्लों के लिए है।

Here the noun changes because it is now plural:

• singular oblique: पिल्ले
• plural oblique: पिल्लों

So:

• पिल्ले के लिए = for the puppy
• पिल्लों के लिए = for the puppies

If you wanted to say The vaccines are for the puppies, then both the subject and the verb would change:

टीके पिल्लों के लिए हैं।

This is a very useful distinction.

• पिल्ले के लिए टीका = a vaccine for the puppy
  This focuses on purpose or intended recipient.

• पिल्ले का टीका = the puppy’s vaccine
  This sounds more like possession or association.

So के लिए means for, while का / की / के often shows possession or relationship.

Yes, absolutely.

यह टीका पिल्ले के लिए है। means This vaccine is for the puppy.

The original sentence टीका पिल्ले के लिए है। is already grammatical, but adding यह makes it more specific if you are pointing to a particular vaccine.

So both are possible:

• टीका पिल्ले के लिए है। = The vaccine is for the puppy.
• यह टीका पिल्ले के लिए है। = This vaccine is for the puppy.
