כל מי שרוצה להשתתף צריך להצביע לפני שהוא מדבר.

כל מי is a very common Hebrew expression meaning everyone who, anyone who, or whoever.

• כל = all / every
• מי = who

So כל מי שרוצה is literally something like every person who wants.

In natural English, depending on context, you might translate it as:

• everyone who wants
• anyone who wants
• whoever wants

In instruction-like sentences such as this one, English often prefers anyone who.

The prefix ש־ is a very common connector in modern Hebrew. It can mean things like that, who, or which, depending on context.

Here:

• מי שרוצה = who wants
• לפני שהוא מדבר = before he speaks

So in this sentence, ש־ introduces a clause:

• שרוצה = that/who wants
• שהוא מדבר = that he is speaking / that he speaks

It is basically the everyday Hebrew equivalent of the more formal אשר.

This is the common Hebrew pattern:

צריך + infinitive

It means:

• needs to ...
• has to ...
• must ...

So:

• צריך להצביע = needs to vote / has to raise a hand / must indicate

The word צריך agrees with the subject, and the second verb stays in the infinitive:

• אני צריך ללכת = I need to go
• היא צריכה לקרוא = she needs to read
• הם צריכים לחכות = they need to wait

Because כל מי is treated grammatically as singular.

Even though the meaning is broad and refers to any person in general, Hebrew handles it like every person who..., not like a plural group.

That is why the sentence uses singular forms:

• צריך
• הוא
• מדבר

This is similar to English using singular grammar with everyone:

• Everyone is ready not
• Everyone are ready

So כל מי שרוצה להשתתף צריך... is standard Hebrew.

להשתתף is the infinitive to participate.

A few useful points:

• the initial ל־ is the normal marker for the infinitive, like English to
• the verb is from the root ש־ת־ף, which has to do with sharing/participation
• the form belongs to the התפעל pattern

So:

• רוצה להשתתף = wants to participate

This is a very common verb in classroom, meeting, and discussion contexts.

להצביע can have several related meanings, including:

• to vote
• to point
• to indicate
• to raise one’s hand

In this sentence, the exact meaning depends on context.

Because the sentence also mentions speaking, many learners would understand it as something like:

• raise your hand before speaking
• signal before speaking

But if the context is a formal meeting or election, it could really mean to vote.

So this is one of those verbs where context matters a lot.

Because Hebrew commonly uses:

לפני ש... + a full clause

to mean before ...

So:

• לפני שהוא מדבר = before he speaks

Here:

• לפני = before
• שהוא = that he / he
• מדבר = speaks / is speaking

This is a very natural Hebrew structure. English often uses a simpler form, but Hebrew often prefers a full clause after לפני.

Hebrew often uses the present tense in time clauses like this, especially when describing a general rule, routine, or procedure.

So:

• לפני שהוא מדבר literally looks like before he is speaking
• but in natural English it is usually before he speaks

In other words, the Hebrew present tense here does not mean the action is happening right now in a narrow sense. It can describe the act in a general procedural way.

This is very normal in instructions and rules.

Hebrew often uses the masculine singular as the default form when the person is generic, unknown, or mixed.

That is why this sentence has:

• צריך
• הוא
• מדבר

If you were clearly referring to a female participant, you would say:

כל מי שרוצה להשתתף צריכה להצביע לפני שהיא מדברת.

A useful detail: רוצה is written the same way for masculine and feminine singular in unpointed Hebrew, but the pronunciation changes:

• masculine: rotze
• feminine: rotza

So in writing, the clearest visible changes are usually:

• צריך → צריכה
• הוא → היא
• מדבר → מדברת
