במילון הזה כל אות גדולה וברורה, ולכן קל לקרוא בו.

במילון is a combination of:

• ב־ = in
• המילון = the dictionary

When ב־ is attached to a word with ה־ (the), they often contract:

• ב + המילון → במילון

So במילון הזה means in this dictionary.

This is very common in Hebrew:

• בבית = in the house
• בספר = in the book
• במכונית = in the car

The ה is not really gone in meaning; it is absorbed into the form.

In modern Hebrew, the normal way to say this dictionary is:

• המילון הזה

With a preposition, that becomes:

• במילון הזה

Hebrew usually uses the definite noun plus הזה / הזאת / האלה for this / these.

So:

• המילון הזה = this dictionary
• הספר הזה = this book
• הילדה הזאת = this girl

Using מילון זה sounds more formal, literary, or old-fashioned.

כל can work in different ways, and that changes the meaning.

Here, כל אות means every letter.
That is why the noun is singular:

• כל אות גדולה וברורה = every letter is big and clear

Compare:

• כל אות = every letter
• כל האותיות = all the letters

So the sentence is focusing on each letter individually, not on the letters as a group.

Because אות is a feminine noun in Hebrew.

Adjectives must agree with the noun in gender and number, so:

• אות = feminine singular
• גדולה = feminine singular
• ברורה = feminine singular

If the noun were masculine, the adjectives would also be masculine. For example:

• ספר גדול וברור = a big and clear book

But here:

• אות גדולה וברורה = a big and clear letter

Yes. In the present tense, Hebrew usually does not use a separate word for is / are.

So:

• כל אות גדולה וברורה

literally looks like:

• every letter big and clear

but it means:

• every letter is big and clear

This is normal Hebrew sentence structure in the present tense.

Compare:

• הילד עייף = the boy is tired
• החדר קטן = the room is small
• האות ברורה = the letter is clear

ולכן means and therefore, so, or and so.

It is made of:

• ו־ = and
• לכן = therefore / so

So the sentence structure is:

• Every letter is large and clear, and therefore it is easy...

It connects the first idea to the result:

• the letters are large and clear
• therefore, reading is easy

קל means easy, and לקרוא means to read.

Together, קל לקרוא literally means:

• easy to read

Hebrew often uses this pattern:

• קל + infinitive = easy to ...
• קשה + infinitive = hard to ...
• נעים + infinitive = pleasant to ...

Examples:

• קל להבין = easy to understand
• קשה ללמוד = hard to study
• נעים לשמוע = pleasant to hear

In this sentence, Hebrew does not need a separate it is.
So ולכן קל לקרוא בו means and therefore it is easy to read in it / read from it.

This is a very important Hebrew usage.

With things like books, newspapers, dictionaries, magazines, and texts, Hebrew often uses the verb לקרוא with the preposition ב־:

• לקרוא בספר = to read a book
• לקרוא בעיתון = to read the newspaper
• לקרוא במילון = to read in a dictionary

So בו means in it, referring back to מילון.

In English, we usually just say read it, but Hebrew often thinks of reading as reading in a text.

So:

• קל לקרוא בו = literally easy to read in it
• natural English meaning: easy to read

Because it refers to מילון, and מילון is masculine.

בו is made of:

• ב־ = in
• הוא-type pronoun form = him/it

So:

• בו = in it for a masculine singular noun

If the noun were feminine, Hebrew would use בה:

• בספרייה... קל לקרוא בה = in the library... it is easy to read there/in it

Here:

• מילון = masculine
• therefore בו

Yes. The verb לקרוא can mean either:

• to read
• to call

The meaning depends on context.

Here, because the sentence is about letters in a dictionary, the meaning is clearly to read.

Examples:

• לקרוא ספר = to read a book
• לקרוא בשם = to call by a name
• הוא קרא לי = he called me
• הוא קרא את הספר = he read the book

So in this sentence, לקרוא בו can only mean to read in it.

Hebrew often places a prepositional phrase at the beginning to set the scene or topic.

So:

• במילון הזה = in this dictionary

comes first, and then the sentence says what is true there:

• כל אות גדולה וברורה

This is very natural Hebrew word order. A more English-like order would not sound as natural.

The sentence is organized like this:

• In this dictionary
• every letter is large and clear
• therefore it is easy to read in it

So the Hebrew word order is not strange; it is just following a common Hebrew way of presenting information.
