המורה אמרה שלא צריך לדבר מהר; חשוב יותר לדבר ברור.

Because the verb agrees with the speaker, and אמרה is she said. The noun המורה can mean either the teacher (male or female), but the verb tells you this teacher is female here.

• המורה אמרה = the teacher (female) said
• המורה אמר = the teacher (male) said

Not by itself. המורה can refer to either a male teacher or a female teacher. Hebrew often makes the gender clear through the verb or other words in the sentence.

So in this sentence, you know the teacher is female because of אמרה.

שלא is made from ש־ + לא.

• ש־ = that
• לא = not

So שלא צריך לדבר מהר means something like that there is no need to speak quickly or that one shouldn’t speak quickly, depending on context.

In this sentence, it is introducing what the teacher said.

Here צריך is being used in an impersonal, general way, like:

• it is necessary
• one needs to
• you need to in a general sense

In Hebrew, this kind of general statement is very often left in the masculine singular form צריך.

So לא צריך לדבר מהר does not necessarily mean he doesn’t need to speak quickly. Here it means something more general, like:

• there’s no need to speak quickly
• you don’t need to speak quickly

If the sentence were clearly about a specific woman, you might see לא צריכה, but the masculine singular is very common in general statements.

Because Hebrew often leaves the subject unstated in general expressions.

לא צריך לדבר מהר literally looks like not necessary to speak fast, but in natural English it becomes:

• you don’t need to speak fast
• there’s no need to speak fast

This is a very common Hebrew pattern: צריך + infinitive.

Because each clause has its own verb phrase:

• לא צריך לדבר מהר = there’s no need to speak quickly
• חשוב יותר לדבר ברור = it’s more important to speak clearly

So the sentence contrasts two things:

1. speaking quickly
2. speaking clearly

Repeating לדבר makes that contrast explicit and natural in Hebrew.

לדבר is the infinitive, meaning to speak.

The pattern here is very common:

• צריך + infinitive
• חשוב + infinitive

Examples:

• צריך ללמוד = it is necessary to study / you need to study
• חשוב להבין = it is important to understand

So:

• צריך לדבר = need to speak
• חשוב יותר לדבר = it is more important to speak

מהר means quickly or fast, and here it functions as an adverb.

So:

• לדבר מהר = to speak quickly / fast

Even though English clearly separates adjectives and adverbs, Hebrew is sometimes less strict in everyday usage. But in this case, מהר is the standard way to say quickly.

This is a great question, because it sounds unusual to English speakers.

ברור literally means clear, but in spoken and informal Hebrew it is very common to use an adjective like this adverbially after a verb.

So:

• לדבר ברור = to speak clearly

More formal alternatives could be:

• לדבר בבירור
• לדבר בצורה ברורה
• לדבר באופן ברור

But לדבר ברור is very natural in everyday Hebrew.

Because when an adjective is used this way adverbially, Hebrew often uses the masculine singular form as the default.

So even if the teacher is female, לדבר ברור still stays ברור, because it describes the manner of speaking, not the gender of the person speaking.

This is similar to how צריך was used in a default/general masculine singular form.

Literally, חשוב יותר means more important.

In the sentence:

• חשוב יותר לדבר ברור

the meaning is:

• it is more important to speak clearly

Hebrew often omits the equivalent of English it is in this kind of sentence. So the literal structure is closer to:

• more important to speak clearly

but natural English adds it is.

It actually does, but through contrast rather than a full comparison structure.

The first part says:

• there’s no need to speak quickly

The second part says:

• it’s more important to speak clearly

So יותר means more, and the comparison is understood from the previous clause: more important than speaking fast.

Hebrew often leaves that comparison implicit when the contrast is already obvious.

The semicolon separates two closely related ideas:

• לא צריך לדבר מהר
• חשוב יותר לדבר ברור

It shows a stronger break than a comma, but the ideas still belong together.

In less formal writing, many people would also use a comma:

• המורה אמרה שלא צריך לדבר מהר, חשוב יותר לדבר ברור.

The semicolon just makes the contrast a bit clearer and neater.

It is mostly natural everyday Hebrew.

A few notes:

• המורה אמרה — completely normal
• שלא צריך לדבר מהר — very common spoken and written Hebrew
• לדבר ברור — especially natural in everyday speech

If you wanted a slightly more formal version, you might say:

• המורה אמרה שאין צורך לדבר מהר; חשוב יותר לדבר בבירור.

But the original sentence sounds very natural and conversational.

Yes, depending on context, Hebrew לא צריך can sometimes sound like either:

• don’t need to
• shouldn’t

In this sentence, because of the second clause חשוב יותר לדבר ברור, the idea is probably:

• You don’t have to speak fast; it’s more important to speak clearly.

So the focus is more on lack of necessity than on a strict prohibition.
