החתול רץ פנימה.

A common pronunciation is:

ha-kha-TUL rats pe-NI-ma

More carefully:

• החתול = ha-khatul
• רץ = rats
• פנימה = penima

Notes:

• The ח in החתול is a throaty sound, like the ch in German Bach or Scottish loch, not like English h.
• ץ at the end of רץ sounds like ts.
• The stress is usually on the last syllable in החתול and פנימה.

The ה is the Hebrew definite article, meaning the.

So:

• חתול = cat
• החתול = the cat

This ה is attached directly to the noun, unlike English, where the is a separate word.

רץ is the masculine singular present-tense form of the verb לרוץ (to run).

So רץ means:

• runs
• is running

In Hebrew, the present tense often covers both the simple present and the present progressive, depending on context.

Because חתול is grammatically masculine singular, רץ matches it.

Then the verb would usually change to רצה.

So you could say:

• החתולה רצה פנימה. = The female cat runs/is running inside.

Or, if you still used חתול for some reason but meant a feminine subject, the verb would still normally need to agree in gender:

• masculine singular: רץ
• feminine singular: רצה

Hebrew verbs in the present tense agree with the subject in gender and number.

פנימה means inward, inside, or to the inside.

In this sentence, it gives the sense of motion into a place rather than just being located there.

So רץ פנימה is something like:

• runs inside
• runs inward
• runs in

It suggests movement from outside or from one area into an inner space.

This is a very common question.

• פנימה usually emphasizes movement inward: inside / inward / into
• בפנים usually means inside as a location: indoors / inside

Examples:

• החתול רץ פנימה. = The cat ran/runs inside (movement inward)
• החתול בפנים. = The cat is inside (location)

So in your sentence, פנימה is a good choice because the cat is moving.

This is a normal and natural Hebrew word order:

subject + verb + adverb/direction

So:

• החתול = subject
• רץ = verb
• פנימה = direction/adverb

Hebrew word order is often flexible, but this order is very standard and neutral.

Other orders can be possible in special contexts for emphasis, but החתול רץ פנימה is the basic, straightforward way to say it.

In a sense, yes. Hebrew often expresses direction with a special ending or form rather than a separate word like English to.

פנימה already contains the idea of motion toward the inside.

That is why the sentence does not need a separate preposition to mean into or inside here.

Yes.

Hebrew present tense does not usually make the same distinction English does between:

• runs
• is running

So החתול רץ פנימה could mean either:

• The cat runs inside
• The cat is running inside
• The cat runs inward

The exact meaning depends on context.

The dictionary forms are:

• החתול → dictionary form: חתול (cat)
• רץ → dictionary form: לרוץ (to run)
• פנימה → dictionary/base idea: פנים / directional form פנימה (inside, inward)

When looking words up, you usually remove the ה from nouns and identify the verb by its infinitive.

Yes, חתול is normally a masculine noun meaning cat.

If you specifically want to say female cat, Hebrew often uses:

• חתולה

So:

• חתול = male cat / cat (masculine form)
• חתולה = female cat

Because your sentence has חתול, the verb appears in masculine singular: רץ.

Not by itself in standard grammar.

רץ is specifically a present-tense form.

For comparison:

• Present: החתול רץ פנימה. = The cat runs / is running inside.
• Past: החתול רץ פנימה would not normally be past; instead you would use a past form such as החתול רץ פנימה only if context was extremely unusual, but standard past would be החתול רץ פנימה? No — the proper past is החתול רץ only in present. A clearer past sentence would be החתול רץ פנימה not acceptable as standard past; use החתול רץ? Better: החתול רץ is still present. Standard past from לרוץ is החתול רץ? Actually the past masculine singular is רץ only for present; past masculine singular is רץ in some verbs? No, for לרוץ past 3ms is רָץ, which is written the same way as present רץ in unvocalized Hebrew.
• Future: החתול ירוץ פנימה. = The cat will run inside.

Important detail: in unpointed Hebrew, the past he ran and present runs/is running can sometimes be written the same way: רץ. Usually context tells you which one is meant. In a simple sentence like this, learners are often expected to read it as present unless context suggests past.

Modern Hebrew is usually written without vowel marks in everyday texts.

So the sentence appears as:

• החתול רץ פנימה

A beginner might expect something like full vowel marking, but that is mostly used in:

• children's books
• poetry
• dictionaries
• language-learning materials
• religious texts
• places where pronunciation needs to be very clear

Native readers usually read these words without needing vowel marks.

No, it is perfectly normal and natural.

It is not strange or overly literary. You can hear it in everyday Hebrew, especially when talking about movement:

• בוא פנימה = Come in
• היכנס פנימה = Go inside / enter

So in your sentence, פנימה sounds natural and idiomatic.
