היא צודקת: אם יש ערפל, כדאי לנסוע לאט יותר.

A natural pronunciation is:

Hi tsodéket: im yesh arafél, kedái linsóa le’at yotér.

A few notes:

• היא = hi
• צודקת = tsodéket
• אם = im
• יש = yesh
• ערפל = arafél
• כדאי = kedái
• לנסוע = linsóa
• לאט = le’at
• יותר = yotér

היא צודקת means she is right.

The adjective צודקת is feminine singular, so it matches היא (she). Compare:

• היא צודקת = she is right
• הוא צודק = he is right
• הם צודקים = they are right
• הן צודקות = they are right (feminine)

So this is a good example of gender agreement in Hebrew adjectives.

Hebrew usually uses צודק / צודקת for right in the sense of correct.

So:

• היא צודקת = she is right / she is correct

נכון / נכונה can also mean correct, but it is often used for:

• facts
• statements
• answers
• something being true or correct

Examples:

• זה נכון = that is correct / true
• היא צודקת = she is right

So in this sentence, צודקת is the natural choice.

יש means there is / there are.

So:

• יש ערפל = there is fog
• אם יש ערפל = if there is fog

English uses there is, but Hebrew uses the single word יש.

This is a very common pattern:

• יש זמן = there is time
• יש בעיה = there is a problem
• יש מכוניות ברחוב = there are cars in the street

English often says things like:

• it is raining
• it is foggy

Hebrew often uses a different structure. Here it says:

• אם יש ערפל = if there is fog

So instead of using a dummy subject like English it, Hebrew simply says there is fog.

A more adjective-like weather sentence can exist in some cases, but יש ערפל is very natural and common.

Because the sentence means fog in a general sense, not the fog.

• ערפל = fog
• הערפל = the fog

So:

• אם יש ערפל = if there is fog
• אם יש הערפל would not be natural here

You use ה־ when talking about something specific and known:

• הערפל כבד הבוקר = the fog is heavy this morning

כדאי means something like:

• it is advisable
• it is a good idea
• it is worth

In this sentence:

• כדאי לנסוע לאט יותר = it is advisable to drive more slowly

A very common Hebrew structure is:

כדאי + infinitive

Examples:

• כדאי ללכת = it’s כדאי to go / it’s a good idea to go
• כדאי לחכות = it’s advisable to wait
• כדאי לבדוק = it’s worth checking

Hebrew often leaves that unstated when the meaning is general.

So כדאי לנסוע לאט יותר literally means something like:

• it is advisable to drive more slowly

In context, it usually means:

• one should drive more slowly
• you should drive more slowly

If you want to state the person explicitly, you can:

• כדאי לך לנסוע לאט יותר = you should drive more slowly
• כדאי לנו לנסוע לאט יותר = we should drive more slowly

So the original sentence gives general advice.

Because after כדאי, Hebrew usually uses the infinitive.

So the pattern is:

• כדאי + infinitive

Here:

• לנסוע = to drive / to travel
• כדאי לנסוע = it is advisable to drive / travel

This is similar to English:

• It’s good to wait
• It’s worth checking

Hebrew uses the infinitive very often after modal-like words such as כדאי.

לנסוע literally means to travel / to go by vehicle.

Depending on context, it can mean:

• to drive
• to ride
• to travel by car/bus/train
• sometimes simply to go by vehicle

In this sentence, because of the road-safety context and לאט יותר, English naturally translates it as drive more slowly.

So the Hebrew is slightly broader than English here, but drive is the best natural translation in context.

Both can be understood, but לאט יותר is the more natural and common order here.

• לאט יותר = more slowly
• יותר לאט can also occur, but it often sounds a bit more marked or contrastive depending on context

So for a learner, לאט יותר is the safest standard pattern.

Similar examples:

• מהר יותר = faster
• חזק יותר = stronger / louder
• טוב יותר = better

לאט is an adverb, meaning slowly.

Examples:

• הוא מדבר לאט = he speaks slowly
• סע לאט = drive slowly
• ללכת לאט = to walk slowly

Hebrew often uses simple adverb forms like this without adding an ending like English -ly.

Yes, but it would sound more formal or less everyday in many contexts.

• לאט = slowly
• באיטיות = slowly / with slowness, more formal

So:

• כדאי לנסוע לאט יותר sounds natural and everyday
• כדאי לנסוע באיטיות רבה יותר sounds more formal or written

For normal spoken Hebrew, לאט יותר is the better choice.

אם means if, so it introduces a condition:

• אם יש ערפל, כדאי לנסוע לאט יותר = if there is fog, it’s advisable to drive more slowly

כש means when:

• כשיש ערפל, כדאי לנסוע לאט יותר = when there is fog, it’s advisable to drive more slowly

The difference is small but real:

• אם = conditional, possible situation
• כש = whenever / when that situation happens

Both can make sense, but אם matches the English if most directly.

The colon introduces an explanation or justification.

So:

• היא צודקת: אם יש ערפל, כדאי לנסוע לאט יותר. means:
• She is right: if there is fog, it’s advisable to drive more slowly.

The part after the colon explains why she is right.

A dash or even a full stop could also appear in other writing styles, but the colon works well here.

Yes, Hebrew word order is somewhat flexible.

The original order:

• אם יש ערפל, כדאי לנסוע לאט יותר.

You could also say:

• כדאי לנסוע לאט יותר אם יש ערפל.

Both are grammatical. The original version puts the condition first, which is very natural because it sets the situation before the advice.

It is neutral, natural Hebrew.

Nothing in it is especially slangy or especially formal:

• אם יש ערפל is standard
• כדאי לנסוע לאט יותר is standard and common
• היא צודקת is everyday natural Hebrew

So this is a good sentence to learn as a normal, standard pattern.
