पालतू जानवर इलाज से ठीक होता है।

A natural word-by-word breakdown is:

• पालतू = pet, domesticated, tamed
• जानवर = animal
• इलाज = treatment, medical care
• से = by, with, through, from
• ठीक = fine, well, cured, better
• होता है = happens, becomes, is in a general/habitual sense

So the sentence is literally something like:

A pet animal becomes well through treatment.

Hindi normally puts the main verb near the end. A very common pattern is:

subject + other information + verb

So here:

• पालतू जानवर = subject
• इलाज से = by/through treatment
• ठीक होता है = becomes well / gets better

This is much more natural in Hindi than putting the verb earlier.

से is a very common postposition in Hindi. In this sentence, it shows the means, cause, or method.

So इलाज से means:

• through treatment
• with treatment
• by treatment
• as a result of treatment

English uses prepositions before the noun, but Hindi usually uses postpositions after the noun. That is why Hindi says इलाज से, not something equivalent to by treatment with the marker before the word.

This is an important difference.

• ठीक है = is fine / is okay / is well
• ठीक होता है = becomes well / gets better / is generally cured

So ठीक है describes a present state. But ठीक होता है suggests a process, result, or general truth.

In this sentence, the idea is not just the pet is well, but rather the pet gets well because of treatment.

The verb agrees with the subject in gender and number.

Here the subject is जानवर, which is treated as:

• singular
• usually masculine in this kind of generic sentence

So the form is:

• होता है = masculine singular

Compare:

• पालतू बिल्ली इलाज से ठीक होती है। = A pet cat gets better with treatment.
  (बिल्ली is feminine singular)
• पालतू जानवर इलाज से ठीक होते हैं। = Pet animals get better with treatment.
  (plural)

It can mean pet animal or domesticated animal, depending on context.

• पालतू = domesticated / kept by humans
• जानवर = animal

So together, पालतू जानवर is understandable as pet animal.

In everyday speech, people may also say:

• पालतू कुत्ता = pet dog
• पालतू बिल्ली = pet cat

If the speaker wants to be more specific, they often name the animal directly.

It is most naturally understood as a general statement.

Hindi often uses a singular noun to express a general truth, much like English can say:

• A pet gets better with treatment.

So पालतू जानवर here does not have to mean one specific animal. It can mean a pet animal in general.

Context decides whether it is:

• generic: a pet animal / pet animals generally
• specific: the pet animal

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

That means जानवर can mean:

• an animal
• the animal
• animal in a general sense

You figure out which meaning is intended from context.

So पालतू जानवर could mean:

• a pet animal
• the pet animal
• pet animals in general

Yes, पालतू जानवर इलाज से ठीक हो जाता है। is also possible, and many learners may actually find it easier to understand.

There is a small nuance:

• ठीक होता है = becomes well / gets well / is cured, often sounding general or habitual
• ठीक हो जाता है = gets well, recovers, ends up becoming well; often emphasizes the completed change

So:

• ठीक होता है can sound a bit more general or descriptive
• ठीक हो जाता है can sound a bit more result-focused

Both are understandable, but ठीक हो जाता है is often very natural when talking about recovery.

A simple transliteration is:

paaltū jaanvar ilaaj se ṭhīk hotā hai

A few pronunciation notes:

• पालतू: paa-l-too
• जानवर: jaa-nvar or jaa-na-var, depending on speech speed
• इलाज: i-laaj
• ठीक: ṭheek; the ठ is a retroflex sound
• होता: ho-taa

The long vowels matter:

• आ = long aa
• ई = long ee
• ऊ = long oo

Yes, it is grammatical and understandable.

That said, depending on context, a native speaker might also say something slightly different, such as:

• पालतू जानवर इलाज से ठीक हो जाता है।
• इलाज से पालतू जानवर ठीक हो जाता है।
• इलाज करने से पालतू जानवर ठीक हो जाता है।

These versions are close in meaning. The original sentence is still a valid and useful model for learning:

• subject: पालतू जानवर
• means/cause: इलाज से
• result: ठीक होता है
