לא משנה מי תדבר ראשונה, חשוב שכולן יקשיבו זו לזו.

Because the sentence is talking about a group of females.

Hebrew marks gender much more often than English does. Here, the speaker is referring to women or girls, so several words appear in the feminine form:

• תדבר = she will speak
• ראשונה = first in the feminine singular
• כולן = all of them for a feminine group
• יקשיבו = they will listen; this form can look the same for masculine and feminine in many future-tense plural forms, but כולן makes it clear the group is feminine

If the group were masculine or mixed, you would normally expect:

• ראשון instead of ראשונה
• כולם instead of כולן

לא משנה is a very common expression meaning it doesn’t matter.

Literally, משנה comes from the verb לשנות in the sense of to make a difference / to matter. In this expression, Hebrew uses a fixed third-person singular form, similar to how English says it doesn’t matter, even when no explicit it appears.

So:

• לא משנה מי תדבר ראשונה = It doesn’t matter who speaks first

This expression is extremely common in spoken and written Hebrew.

Because מי means who, and here it refers to whoever it is among the women/girls. Hebrew often matches the verb to the expected gender/number of the person being referred to.

So:

• מי תדבר = who will speak / whoever speaks, referring to a female singular person
• מי ידבר would usually sound masculine
• מי תדברי would mean who will you (feminine singular) speak, which does not fit here at all

In other words, מי itself does not show gender, but the verb after it can.

Because ראשונה describes the person who speaks first, and that person is a single individual.

Even though the overall sentence involves several people, only one of them can be the first speaker. So Hebrew uses the feminine singular form:

• ראשונה = first for one female
• If it referred to one male, it would be ראשון

So the logic is:

• group = כולן
• one member of the group = מי תדבר ראשונה

The ש is a very common Hebrew conjunction meaning that.

So:

• חשוב = important
• חשוב שכולן יקשיבו = It is important that they all listen

This ש introduces a subordinate clause, just like English that does in many sentences.

You will see this structure all the time:

• חשוב ש... = It is important that...
• טוב ש... = It is good that...
• חבל ש... = It’s a shame that...

כולן means all of them for a feminine plural group.

A few useful distinctions:

• כולן = all of them (feminine)
• כולם = all of them (masculine or mixed)
• כל ה... = all the..., followed by a noun
  For example: כל הבנות = all the girls

So here, since no noun follows and the sentence means all of them, כולן is the correct form.

As for spelling: modern standard spelling normally uses כולן with ו.

זו לזו means to one another or to each other, specifically for females.

This is a reciprocal expression. It shows that the action goes both ways among members of the group.

Here:

• יקשיבו זו לזו = they should listen to one another / each other

Because the group is feminine, Hebrew uses feminine forms:

• זו = feminine this/one
• לזו = to this one / to one another in this reciprocal structure

For masculine or mixed groups, you may see:

• זה לזה = to one another

Because the verb להקשיב takes the preposition ל, meaning to listen to someone.

So in Hebrew you do not usually say simply להקשיב מישהי. You say:

• להקשיב למישהי = to listen to someone

That is why the reciprocal phrase also includes ל:

• זו לזו = literally something like one to another
• after יקשיבו it means listen to one another

This is a good thing to memorize with the verb:

• להקשיב ל... = to listen to...

This is very normal in Hebrew.

After words like חשוב, Hebrew often uses the future tense where English might use should or a subjunctive-like structure:

• חשוב שכולן יקשיבו = literally It is important that they will listen
• natural English: It is important that they listen or should listen

So the Hebrew future tense here does not necessarily indicate simple future time. It often expresses:

• a desired action
• a recommendation
• an expectation

This is a very common pattern.

Sometimes, but it would not sound exactly the same.

• לא משנה is the most natural and common way to say it doesn’t matter
• לא חשוב can also mean it’s not important, but that is slightly different in tone and structure

In this sentence, לא משנה מי תדבר ראשונה is the idiomatic choice.

Compare:

• לא משנה מי תדבר ראשונה = It doesn’t matter who speaks first
• לא חשוב מי תדבר ראשונה = understandable, but less natural here for many speakers

The comma separates two parts:

1. לא משנה מי תדבר ראשונה
2. חשוב שכולן יקשיבו זו לזו

The first part sets up a condition or background idea: it doesn’t matter who speaks first.
The second part gives the main point: what matters is that they all listen to each other.

So the comma helps organize the sentence and makes it easier to read.

Formally, תדבר is a future-tense form: she will speak.

But in sentences with מי, especially in statements like this, it can feel broader than simple future time. It can mean something like:

• who speaks first
• whoever speaks first
• who will speak first

So although the form is future, the meaning can be more general or less strictly tied to a specific future moment.

The sentence as written is natural and clear:

• לא משנה מי תדבר ראשונה, חשוב שכולן יקשיבו זו לזו.

Hebrew does allow some flexibility, but not every rearrangement sounds equally natural.

For example, you could emphasize the second idea in other ways, but the original version is smooth because it first dismisses the unimportant issue, then states the important one:

• It doesn’t matter who speaks first; what’s important is that everyone listens to each other.

So the word order supports the logic of the sentence:

1. unimportant point
2. important point
