כשהמורה כותבת על הלוח, אנחנו מעתיקים מהר למחברת.

כשהמורה means when the teacher or while the teacher.

The piece כש־ is a very common short form meaning when. It often attaches directly to the following word:

• כשהמורה = when the teacher
• compare with the longer form כאשר המורה

So in this sentence, כשהמורה כותבת על הלוח means when/while the teacher is writing on the board.

Because המורה here is understood as a female teacher.

In Hebrew present tense, the verb agrees with the subject in gender and number:

• כותב = writing / writes, masculine singular
• כותבת = writing / writes, feminine singular

Since the sentence uses כותבת, the teacher is female. If it were a male teacher, it would be:

• כשהמורה כותב על הלוח...

It can mean either one.

Hebrew present-tense forms often cover both the English simple present and present progressive:

• היא כותבת = she writes / she is writing

So here כשהמורה כותבת על הלוח can mean:

• when the teacher writes on the board
• while the teacher is writing on the board

The exact nuance comes from context.

על means on, and הלוח means the board.

So:

• על הלוח = on the board

לוח is a board or writing surface. In a classroom, it usually means the blackboard or whiteboard.

Because Hebrew is saying the board, not just a board.

The prefix ה־ is the definite article, equivalent to English the:

• לוח = a board / board
• הלוח = the board

In a classroom sentence like this, the board is usually a specific, known one, so the board makes sense.

מעתיקים means copy or are copying.

It comes from the verb להעתיק, which often means:

• to copy
• to copy down
• to transcribe

In this sentence, it means copying what the teacher writes.

Because מעתיקים is the masculine plural present form, and Hebrew uses masculine plural as the default for:

• a group of males
• a mixed group
• a group whose gender is unspecified

So:

• אנחנו מעתיקים = we copy / we are copying (masculine plural, or mixed group)
• אנחנו מעתיקות = we copy / we are copying (all-female group)

מהר means quickly or fast.

It is functioning as an adverb, describing how we copy:

• אנחנו מעתיקים מהר = we copy quickly

It does not change for gender or number.

Both can be possible in Hebrew, but they give slightly different feels.

Here, למחברת is very natural with verbs like write or copy, because it can express the idea of writing/copying into the notebook, as the destination of the writing.

• למחברת = into/to the notebook
• במחברת = in the notebook

In many classroom contexts, למחברת sounds very natural for copying something down into a notebook.

Great question. With the prepositions ב־, כ־, and ל־, the definite article ה־ merges into the preposition.

So in pointed Hebrew:

• לְמַחְבֶּרֶת = to a notebook
• לַמַּחְבֶּרֶת = to the notebook

But in normal unpointed writing, both are written the same way:

• למחברת

So the meaning is determined by context. In this sentence, the context can naturally suggest the notebook or simply a notebook / the notebook we’re using.

It can be either, depending on context.

Hebrew present tense is flexible, and כש can introduce:

• a general repeated action: When the teacher writes on the board, we copy quickly into the notebook
• a current situation: While the teacher is writing on the board, we are copying quickly into the notebook

Without more context, both readings are possible.

Hebrew often puts a when/while clause first, just like English can:

• כשהמורה כותבת על הלוח, אנחנו מעתיקים מהר למחברת.
• When the teacher writes/is writing on the board, we copy quickly into the notebook.

This word order sounds very natural. It sets the scene first, then gives the main action.

You could also put the main clause first in Hebrew, but this version is completely standard.
