כשהתינוק לא רגוע, אבא מחבק אותו ומנשק אותו כדי להרגיע אותו.

כשהתינוק means when the baby.

It is made of:

• כש־ = when
• התינוק = the baby

In Hebrew, short prepositions and conjunctions are often attached directly to the following word, so instead of writing them separately, you often get one written unit like כשהתינוק.

A longer, more formal version would be כאשר התינוק, but כשהתינוק is very natural and common.

Because in Hebrew, the verb to be is usually omitted in the present tense.

So:

• התינוק לא רגוע literally looks like the baby not calm
• but it means the baby is not calm

This is completely normal in Hebrew.

Compare:

• הוא עייף = he is tired
• היא בבית = she is at home
• התינוק לא רגוע = the baby is not calm

But in the past or future, Hebrew does use forms of to be:

• הוא היה רגוע = he was calm
• הוא יהיה רגוע = he will be calm

Because תינוק is grammatically masculine.

So the adjective must agree with it:

• תינוק רגוע = a calm baby (masculine)
• תינוקת רגועה = a calm baby girl (feminine)

In your sentence:

• התינוק לא רגוע = the baby is not calm

If it were a baby girl, you would normally say:

• כשהתינוקת לא רגועה, אבא מחבק אותה...

Here אבא means Dad, almost like a name or family title, not just the father in a neutral descriptive way.

So:

• אבא = Dad
• האבא = literally the father/dad, which is possible in some contexts, but less natural here

In family-style sentences, Hebrew often uses:

• אמא
• אבא without ה־

So this sentence sounds like:

• When the baby is upset, Dad hugs him...

not

• When the baby is upset, the father hugs him...

אותו means him or sometimes it, depending on context.

In this sentence it refers to the baby, so:

• מחבק אותו = hugs him
• מנשק אותו = kisses him
• להרגיע אותו = to calm him

Because תינוק is masculine, the pronoun is masculine too:

• אותו = him

If it were feminine:

• אותה = her

Hebrew normally repeats the object pronoun with each verb when that pronoun is the object of each verb.

So:

• מחבק אותו = hugs him
• ומנשק אותו = and kisses him
• כדי להרגיע אותו = in order to calm him

This sounds natural and clear in Hebrew.

English sometimes avoids repetition more easily, but Hebrew often keeps it. If you remove the repeated pronouns, the sentence may sound incomplete or less natural.

Because אותו already functions as the direct object pronoun.

With a definite noun, Hebrew often uses את:

• אבא מחבק את התינוק = Dad hugs the baby

But with an object pronoun, you use forms like:

• אותו = him
• אותה = her
• אותם = them (masculine/mixed)
• אותן = them (feminine)

So you say:

• מחבק אותו not
• מחבק את אותו

They are in the present tense, masculine singular.

• מחבק = hugging / hugs
• מנשק = kissing / kisses

In Hebrew, the present tense can express:

1. something happening now
2. a habitual action
3. a general truth

Here it sounds like a habitual or typical action:

• When the baby is not calm, Dad hugs him and kisses him...

So in natural English, this is often translated with the simple present:

• Dad hugs him and kisses him

Because they agree with the subject, which is אבא.

Hebrew present-tense verbs behave a lot like adjectives in agreement:

• masculine singular: מחבק
• feminine singular: מחבקת
• masculine plural: מחבקים
• feminine plural: מחבקות

So:

• אבא מחבק = Dad hugs
• אמא מחבקת = Mom hugs

The same applies to מנשק:

• אבא מנשק
• אמא מנשקת

כדי means in order to.

So:

• כדי להרגיע אותו = in order to calm him

It introduces a purpose:

• Dad hugs and kisses the baby for the purpose of calming him

Hebrew often uses:

• כדי + infinitive

Examples:

• אני לומד כדי להצליח = I study in order to succeed
• היא באה כדי לעזור = she came in order to help

להרגיע means to calm, to soothe, or to calm down someone.

This is important: it is a causative idea — making someone calm.

So:

• להיות רגוע = to be calm
• להרגיע מישהו = to calm someone

In your sentence, Dad is not trying to be calm himself. He is trying to calm the baby.

So:

• כדי להרגיע אותו = in order to calm him / soothe him

Yes. They are closely related.

• רגוע = calm (an adjective)
• להרגיע = to calm / to make calm (a verb)

So the sentence has a nice internal connection:

• התינוק לא רגוע = the baby is not calm
• כדי להרגיע אותו = in order to calm him

English has a similar pattern:

• calm / to calm

Because that first part is a subordinate clause:

• כשהתינוק לא רגוע = when the baby is not calm

Then the main clause follows:

• אבא מחבק אותו...

When a when-clause comes first in Hebrew, a comma is commonly used, just as in English:

• When the baby is not calm, Dad hugs him...

So the punctuation works very similarly here.

Yes. Hebrew allows some flexibility.

For example, you could also say:

• אבא מחבק אותו ומנשק אותו כדי להרגיע אותו כשהתינוק לא רגוע

But the original version is more natural because it sets up the situation first:

• When the baby is not calm, ...

That order is especially common when the first clause gives the condition or time frame for the main action.

Grammatically, אותו can mean him or it depending on what noun it refers to.

Here it refers to התינוק (the baby), so in English we usually translate it as him.

But the Hebrew word itself is simply the masculine singular direct-object pronoun. So if it referred to a masculine noun that is not a person, it could also mean it.

You would change the noun, adjective, and pronouns to feminine forms:

• כשהתינוקת לא רגועה, אבא מחבק אותה ומנשק אותה כדי להרגיע אותה.

Changes:

• התינוק → התינוקת
• רגוע → רגועה
• אותו → אותה

This is a good example of how Hebrew marks gender consistently across the sentence.

A simple pronunciation guide is:

Ksheha-tinok lo ragu'a, aba mechabek oto u-menashék oto k'dei lehargi'a oto.

A few notes:

• כשה sounds like kshe
• תינוק = tinok
• רגוע is roughly ragu'a (with a small break before the last sound)
• מחבק = mechabek
• מנשק = menashek
• כדי is often pronounced k'dei
• להרגיע = lehargi'a

It most naturally sounds like a general or habitual situation:

• When the baby is not calm, Dad hugs him and kisses him in order to calm him.

That is because Hebrew present tense often covers both:

• present ongoing action
• repeated/habitual action

Without additional context, this sentence is understood as a typical pattern, not necessarily one single moment happening right now.
