אני רוצה לקנות שטיח כחול, כי החדר ירגיש חם יותר בחורף.

Yes, Hebrew can sometimes leave out subject pronouns, especially when the verb form already makes the subject clear.

But in the present tense, forms like רוצה do not show person clearly. רוצה could mean I want, you want (masculine singular), or he wants, depending on context. So adding אני makes the meaning clear: I want.

So אני רוצה לקנות... is the most natural way to say I want to buy... here.

In unpointed Hebrew, רוצה can be either:

• masculine singular: rotze
• feminine singular: rotza

So the spelling is the same, but the pronunciation changes. That means this sentence could be said by either a man or a woman. You only know from context, or from vowel marks if they are written.

Because לקנות is the infinitive, meaning to buy.

Hebrew usually uses the infinitive after verbs like want, can, need, like, and so on:

• רוצה לקנות = want to buy
• יכול ללכת = can go
• צריך לעבוד = need to work

The ל־ at the beginning is the normal marker that often appears on Hebrew infinitives.

Because את is used only before a definite direct object.

Here, שטיח כחול means a blue carpet, which is indefinite, so there is no את.

Compare:

• אני רוצה לקנות שטיח כחול = I want to buy a blue carpet
• אני רוצה לקנות את השטיח הכחול = I want to buy the blue carpet

So a very common rule is:

• indefinite object → no את
• definite object → use את

Because in Hebrew, adjectives usually come after the noun they describe.

So:

• שטיח כחול = blue carpet
• בית גדול = big house
• ילדה חכמה = smart girl

This is different from English, where adjectives usually come before the noun.

Because שטיח is a masculine singular noun, so the adjective must agree with it.

Hebrew adjectives agree with the noun in gender and number:

• masculine singular: כחול
• feminine singular: כחולה
• masculine plural: כחולים
• feminine plural: כחולות

So:

• שטיח כחול = a blue carpet
• שמיכה כחולה = a blue blanket

Because החדר is definite: the room.

But שטיח כחול is indefinite: a blue carpet.

Hebrew marks definiteness with ה־:

• חדר = a room / room
• החדר = the room

A useful extra point: if a noun is definite and has an adjective, the adjective also becomes definite:

• השטיח הכחול = the blue carpet

So Hebrew says:

• שטיח כחול = a blue carpet
• השטיח הכחול = the blue carpet

Here כי means because.

It introduces the reason:

• אני רוצה לקנות שטיח כחול = I want to buy a blue carpet
• כי החדר ירגיש חם יותר בחורף = because the room will feel warmer in winter

Be aware that כי can also mean that in some sentences, depending on context. But in this sentence, it clearly means because.

Because the speaker is talking about the result of buying the carpet in the future.

The idea is:

• now: I want to buy
• later, as a result: the room will feel warmer

So Hebrew uses the future form ירגיש = will feel.

Also, ירגיש is third-person masculine singular, because its subject is החדר (the room), and חדר is masculine singular.

This is similar to English expressions like the room will feel warmer. It does not mean the room literally has emotions or physical sensations. It means the room will seem warmer or create a warmer impression.

Hebrew can also say:

• החדר יהיה חם יותר = the room will be warmer

But ירגיש חם יותר often suggests the effect or atmosphere people experience, not just the literal temperature.

יותר means more, and Hebrew uses it to make comparisons.

So:

• חם = warm
• חם יותר = warmer / more warm

Unlike English, Hebrew does not usually add -er to the adjective. It uses יותר instead:

• גדול יותר = bigger
• יפה יותר = prettier / more beautiful
• קר יותר = colder

So חם יותר is the normal Hebrew way to say warmer.

Because חם describes החדר, and חדר is masculine singular.

Even though חם comes after ירגיש, it is still agreeing with החדר:

• החדר ירגיש חם יותר = the room will feel warmer

If the subject were feminine, the adjective would usually be feminine too:

• הדירה תרגיש חמה יותר = the apartment will feel warmer

בחורף means in winter or in the winter, depending on context.

It is built from:

• ב־ = in / at
• חורף = winter

So the basic idea is simply in winter.

One small advanced note: in normal unpointed spelling, forms like בחורף can also represent in the winter, because Hebrew prepositions and the definite article can merge in writing and pronunciation. But at this stage, the easiest way to understand it is just:

• בחורף = in winter

The comma is normal and helpful here because כי introduces a reason clause.

So the sentence is divided into:

• main clause: אני רוצה לקנות שטיח כחול
• reason clause: כי החדר ירגיש חם יותר בחורף

In modern Hebrew, punctuation can be a little flexible, especially in informal writing, but this comma is perfectly natural and standard.
