אני רוצה ללבוש ג'ינס כחולים היום, אבל הם עדיין רטובים מהכביסה.

Because in unpointed Hebrew, רוצה can represent two different present-tense forms:

• masculine singular: רוֹצֶה — I want / he wants
• feminine singular: רוֹצָה — I want / she wants

So אני רוצה can mean:

• I want (said by a man)
• I want (said by a woman)

You only see the difference clearly when there are vowel marks, or when the context makes it obvious.

Because after רוצה (want), Hebrew normally uses an infinitive:

• אני רוצה ללבוש = I want to wear

Here:

• רוצה = want
• ללבוש = to wear

By contrast, לובש / לובשת means wearing or is wearing, not to wear.

So:

• אני רוצה ללבוש ג'ינס = I want to wear jeans
• אני לובש ג'ינס = I am wearing jeans (male speaker)
• אני לובשת ג'ינס = I am wearing jeans (female speaker)

ללבוש means to wear or to put on.

It is the infinitive of the verb built from the root ל־ב־ש, which is connected with clothing and dressing.

Some common forms are:

• ללבוש = to wear / to put on
• לובש = wearing (masculine singular)
• לובשת = wearing (feminine singular)
• לבשתי = I wore / I put on

So in this sentence, ללבוש is the natural form after רוצה.

Because in Hebrew, ג'ינס is commonly treated as a plural item of clothing, like pants in English.

So the adjective has to agree with it in number and gender:

• ג'ינס כחולים = blue jeans

Here כחולים is masculine plural, matching ג'ינס.

Even though English sometimes treats jeans as one item, Hebrew often behaves as if it is plural for agreement purposes in sentences like this.

For the same reason: ג'ינס is being treated as masculine plural.

So Hebrew says:

• הם = they
• רטובים = wet (masculine plural)

That gives:

• אבל הם עדיין רטובים = but they are still wet

This may feel odd to an English speaker because jeans is one clothing item, but English also says they are wet when talking about jeans or pants. Hebrew works similarly here.

Because Hebrew usually does not need a separate expression like a pair of in normal everyday speech.

English often says:

• a pair of jeans
• a pair of pants

But Hebrew commonly just says:

• ג'ינס
• מכנסיים

and then treats them grammatically as plural when needed.

So אני רוצה ללבוש ג'ינס כחולים is a very natural way to say I want to wear blue jeans.

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

So:

• ג'ינס כחולים = blue jeans
• literally: jeans blue

This is the normal Hebrew order.

Also, the adjective must agree with the noun in:

• gender
• number
• definiteness

Here כחולים is masculine plural to match ג'ינס.

Because את is used before a definite direct object, and ג'ינס here is not definite.

Compare:

• אני רוצה ללבוש ג'ינס = I want to wear jeans
  no את, because jeans is indefinite

• אני רוצה ללבוש את הג'ינס הכחולים = I want to wear the blue jeans
  here you do use את, because the blue jeans is definite

So the lack of את is completely normal.

עדיין means still.

In this sentence:

• הם עדיין רטובים = they are still wet

Its position is natural in Hebrew: it comes before the adjective or condition being described.

Other examples:

• אני עדיין עייף = I am still tired
• היא עדיין בבית = She is still at home

So עדיין works very much like English still.

מהכביסה literally means from the laundry or from the wash.

It is made of:

• מ־ = from
• הכביסה = the laundry / the washing

So:

• רטובים מהכביסה = wet from the laundry / wet from being washed

In natural English, this is often translated as still wet from the wash or still wet from doing the laundry.

Because מהכביסה is a combination of:

• מ־ = from
• ה = the
• כביסה = laundry

When Hebrew combines a preposition with the, they often merge into one word:

• מ + ה + כביסה → מהכביסה

This is very common in Hebrew.

Other examples:

• בבית = in the house
• לשולחן = to the table
• מהחנות = from the store

It can mean either, depending on context.

כביסה may refer to:

• laundry as clothes being washed
• the washing/laundry process
• washed clothes

In this sentence, מהכביסה means something like:

• from the laundry
• from the wash
• from being washed

So the idea is that the jeans are still wet because they recently came out of the laundry.

Because in present-tense Hebrew, the verb to be is usually omitted.

So Hebrew says:

• הם רטובים
  literally: they wet
  meaning: they are wet

This is completely normal.

The same pattern appears in many simple present-tense sentences:

• אני עייף = I am tired
• היא שמחה = She is happy
• הם בבית = They are at home

So הם עדיין רטובים naturally means they are still wet.

ג'ינס is pronounced roughly like jeans in English.

The apostrophe after ג shows that the letter should be pronounced like the English j sound, not the regular Hebrew g sound.

So:

• ג = usually g
• ג' = j

This is a common way Hebrew writes foreign sounds in loanwords.

Examples:

• ג'ינס = jeans
• ג'אז = jazz
• ג'ל = gel

Yes. Then the Hebrew would usually be:

• אני רוצה ללבוש את הג'ינס הכחולים היום, אבל הם עדיין רטובים מהכביסה.

Changes:

• את is added because the object is definite
• הג'ינס = the jeans
• הכחולים = the blue ones / blue with the definite article to match the definite noun

In Hebrew, if the noun is definite, the adjective also becomes definite.

Because Hebrew word order is flexible, and this position sounds natural:

• אני רוצה ללבוש ג'ינס כחולים היום = I want to wear blue jeans today

The word היום (today) can appear in different places depending on emphasis. For example:

• היום אני רוצה ללבוש ג'ינס כחולים = Today I want to wear blue jeans
• אני היום רוצה ללבוש ג'ינס כחולים = possible, with a slightly different emphasis

The version in the sentence is a very normal neutral word order.

Yes. רטוב / רטובה / רטובים / רטובות means wet, and it changes to match the noun.

Examples:

• החולצה רטובה = The shirt is wet
• הנעליים רטובות = The shoes are wet
• המכנסיים רטובים = The pants are wet

In your sentence, רטובים is masculine plural because it agrees with ג'ינס.
