בגלל הגשם אני לא רוצה ללכת על המדרכה בלי מטרייה.

בגלל means because of and is followed by a noun phrase:

• בגלל הגשם = because of the rain

By contrast, כי usually means because and is followed by a full clause:

• אני לא רוצה ללכת כי יורד גשם = I don’t want to go because it’s raining

So in your sentence, בגלל is used because the reason is expressed as a noun, הגשם.

The ה־ is the definite article, like the in English.

• גשם = rain
• הגשם = the rain

Hebrew often uses the definite form in places where English might or might not use the. In this sentence, בגלל הגשם is very natural for because of the rain.

Yes, Hebrew can often leave subject pronouns out because the verb form already gives information about the subject.

So both of these can work:

• אני לא רוצה ללכת...
• לא רוצה ללכת...

But אני is often included for clarity, emphasis, or just normal speech rhythm. In a learner sentence, keeping אני in is very helpful and completely natural.

In Hebrew present tense, negation is usually made with לא placed before the verb or verbal adjective:

• רוצה = want / wants
• לא רוצה = do not want / does not want

Hebrew does not use do/does the way English does. So instead of I do not want, Hebrew says literally I not want:

• אני לא רוצה = I don’t want

In unpointed modern Hebrew writing, the masculine and feminine singular forms are often spelled the same:

• masculine pronunciation: rotzé
• feminine pronunciation: rotzá

Both are usually written רוצה without vowel marks.

So the sentence could be said by either a male or female speaker. You only know the gender from context or pronunciation.

After רוצה (want), Hebrew normally uses an infinitive, just like English uses to go after want.

• רוצה ללכת = want to go / want to walk

The ל־ at the beginning of ללכת is the normal infinitive marker, similar to English to in to go.

The dictionary form is ללכת.

One way to think about it is:

• the infinitive marker is ל־
• the verb root/form itself also begins in a way that results in another ל

So you get ללכת with a double ל in spelling. This is normal and not a typo.

It is pronounced roughly la-LE-khet.

It can mean either, depending on context.

• ללכת often means to go
• in some contexts it also means to walk

In this sentence, because it is followed by על המדרכה (on the sidewalk), many learners will naturally understand it as to walk. But Hebrew often uses ללכת where English might say either go or walk.

על usually means on.

• מדרכה = sidewalk
• המדרכה = the sidewalk
• על המדרכה = on the sidewalk

This matches English pretty closely here: walk on the sidewalk.

Yes. מדרכה is a feminine noun.

A final ־ה often marks a feminine noun in Hebrew, though not always. Here:

• מדרכה = feminine singular noun meaning sidewalk

That matters when adjectives or verbs agree with it in other sentences.

Both are possible, but they mean slightly different things.

• בלי מטרייה = without an umbrella / without an umbrella in general
• בלי המטרייה = without the umbrella / a specific umbrella

In your sentence, בלי מטרייה is the natural general meaning: the speaker does not want to walk without carrying an umbrella.

בלי means without.

It can be followed by a noun:

• בלי מטרייה = without an umbrella

It can also be followed by an infinitive in everyday Hebrew:

• בלי לדבר = without speaking

So it is a very useful word to learn.

Both spellings may be seen in modern Hebrew:

• מטרייה
• מטריה

The version with י helps show the pronunciation more clearly. In everyday writing, spelling variation with words like this is common.

The word means umbrella, and it is a feminine noun.

Hebrew word order is fairly flexible.

Your sentence:

• בגלל הגשם אני לא רוצה ללכת על המדרכה בלי מטרייה.

This is natural and emphasizes the reason first: Because of the rain...

Other possible orders include:

• אני לא רוצה ללכת על המדרכה בלי מטרייה בגלל הגשם.
• אני לא רוצה בגלל הגשם ללכת על המדרכה בלי מטרייה.
  This one is less natural in everyday speech, but still understandable.

So the original sentence is good, and it sounds especially natural if the speaker wants to foreground the reason.

Yes. The ה־ is the definite article the, and it is attached directly to the noun:

• הגשם
• המדרכה

In speech, it is pronounced as part of the word, not as a separate word. So Hebrew says one combined form rather than something like the rain as two separate words.

Usually על המדרכה is understood as on the sidewalk, not onto the sidewalk.

If you specifically wanted onto, Hebrew would more often use a phrase that clearly expresses movement toward it, depending on context.

So the most natural understanding of your sentence is:

• being/walking on the sidewalk
• not the act of stepping onto it

Because על already does that job here.

In English, we say walk on the sidewalk. In Hebrew:

• ללכת על המדרכה

The preposition על covers the relation on. Hebrew does not need any extra word there.
