גם בבוקר היה צפוף באוטובוס, ולכן היא החליטה ללכת ברגל.

גם means also, too, or sometimes even, depending on context.

In גם בבוקר היה צפוף באוטובוס, it means also in the morning or in the morning too. It suggests that the bus was crowded at some other time as well, not only in the morning.

Hebrew often puts גם right before the part it is emphasizing. Here it emphasizes בבוקר.

בבוקר means in the morning.

It is made of:

• ב־ = in / at
• הבוקר = the morning

When ב־ joins a noun with ה־ (the), they combine:

• ב + הבוקר = בבוקר

So בבוקר is literally in the morning.

Just בוקר by itself means morning, not in the morning.

This happens because the preposition ב־ joins the definite article ה־.

Underlying form:

• ב + הבוקר

In normal Hebrew spelling, the ה of the article disappears after certain prepositions, and the next letter is strengthened. So it becomes:

• בבוקר

You will see the same pattern in other words too, such as:

• בבית = in the house
• בספר = in the book
• לילד = to the boy
• כמלך = like the king

Here היה צפוף is being used in an impersonal way, like English it was crowded.

There is no explicit noun subject such as the bus in the sentence. Hebrew often uses masculine singular in this kind of general statement:

• היה חם = it was hot
• היה קר = it was cold
• היה צפוף = it was crowded

So this is not really agreeing with she. It is a separate statement about the situation.

If you made the bus the subject explicitly, you could say:

• האוטובוס היה צפוף = the bus was crowded

And if the subject were a feminine noun, agreement would change:

• הרכבת הייתה צפופה = the train was crowded

צפוף means crowded, packed, dense, or cramped, depending on context.

In this sentence, it means the bus was crowded / packed.

It can be used in several ways:

• האוטובוס צפוף = the bus is crowded
• יש לי יום צפוף = I have a busy/packed day
• החדר צפוף = the room is cramped

So the core idea is that there is not much space, or things are tightly packed together.

Because Hebrew normally uses ב־ with buses, cars, trains, and other enclosed vehicles.

So:

• באוטובוס = literally in the bus
• but in natural English we translate it as on the bus

This is just a difference between the languages.

Compare:

• אני באוטובוס = I’m on the bus
• היא ברכבת = she’s on the train
• הם במכונית = they’re in the car

If you said על האוטובוס, that would usually mean on top of the bus, physically on its roof.

לכן means therefore, so, or for that reason.

ולכן is simply:

• ו־ = and
• לכן = therefore

So ולכן means and therefore or and so.

In this sentence, it connects the first part to the result:

• it was crowded on the bus,
• therefore she decided to walk.

Compared with other connectors:

• לכן = therefore, for that reason
• אז = so, then
• בגלל זה = because of that / because of this

לכן / ולכן often sounds a bit more logical or formal than plain אז.

Yes, it could.

Hebrew often allows the subject pronoun to be omitted when the verb already makes it clear. Since החליטה is feminine singular past, it already tells us she decided.

So both are possible:

• ולכן היא החליטה ללכת ברגל
• ולכן החליטה ללכת ברגל

Including היא can make the sentence clearer, smoother, or slightly more explicit. It may also help mark a new clause or keep the listener oriented.

So this is more about style and clarity than strict necessity.

This is a very common Hebrew pattern: a conjugated verb + infinitive.

Here:

• החליטה = she decided
• ללכת = to go / to walk

So:

• החליטה ללכת = she decided to go / to walk

This works much like English:

• הוא התחיל לדבר = he began to speak
• אני רוצה לאכול = I want to eat
• הם ניסו לעזור = they tried to help

The infinitive in Hebrew usually begins with ל־.

It can mean either, depending on context.

ללכת is one of those Hebrew verbs whose exact English translation depends on the situation:

• sometimes to go
• sometimes to walk

In this sentence, because of ברגל, the meaning is clearly to walk / to go on foot.

So the most natural English translation here is she decided to walk.

Literally, ברגל means by foot or with the foot.

But as an expression, ללכת ברגל means:

• to walk
• to go on foot

This is the normal Hebrew idiom.

A useful thing to notice is that Hebrew uses singular רגל here, not plural. That is completely normal:

• ללכת ברגל = to go on foot

You should learn it as a fixed expression.

Hebrew word order is fairly flexible, and putting גם בבוקר first gives it emphasis.

It highlights the idea:

• also in the morning it was crowded

That sounds natural if the previous context already mentioned another time of day, for example:

• it was crowded yesterday evening,
• and also in the morning it was crowded.

So the beginning position helps connect the sentence to the earlier context and gives focus to בבוקר.

Other word orders are possible, but they may shift the emphasis.
