בבוקר שמתי את הסדין ואת השמיכה במכונה עם קצת אבקה.

בבוקר means in the morning.

It is made from:

• ב־ = in
• בוקר = morning

So literally it is in-morning. This is a very common Hebrew way to express time:

• בבוקר = in the morning
• בערב = in the evening
• בלילה = at night

The doubled ב sound happens because the preposition ב־ is attached to a word that already begins with ב plus the article.

שמתי is the past tense, first person singular, of the verb לשים = to put / to place.

So שמתי means:

• I put
• I placed

In Hebrew, the past tense already tells you who did the action, so you do not need a separate word for I unless you want emphasis.

Examples:

• שמתי את הספר על השולחן = I put the book on the table
• שמתי מים בקומקום = I put water in the kettle

In Hebrew, את marks a definite direct object. It does not get translated into English, but it shows that the noun after it is a specific thing.

Here:

• את הסדין = the sheet
• ואת השמיכה = and the blanket

Both nouns are definite because they have ה־ (the), so each one takes את.

This is very normal in Hebrew. When you have two definite direct objects joined by and, Hebrew often repeats את:

• ראיתי את האיש ואת האישה = I saw the man and the woman

If the object is not definite, you usually do not use את:

• שמתי סדין במכונה = I put a sheet in the machine

• סדין = sheet
• שמיכה = blanket

So the sentence is talking about putting bedding into the machine.

A useful note:

• סדין is masculine
• שמיכה is feminine

That matters when adjectives or verbs agree with them in other sentences.

The prefix ה־ is the Hebrew word for the.

So:

• סדין = a sheet / sheet
• הסדין = the sheet

and

• שמיכה = a blanket / blanket
• השמיכה = the blanket

Because the sentence refers to specific items, Hebrew uses the definite article on both nouns.

במכונה literally means in the machine.

It is made from:

• ב־ = in
• מכונה = machine

By itself, מכונה just means machine, but in this sentence the context strongly suggests washing machine.

Hebrew often leaves out words that are obvious from context. So instead of saying במכונת הכביסה (in the washing machine), the sentence simply says במכונה.

עם means with, קצת means a little / some, and אבקה means powder.

So עם קצת אבקה means:

• with a little powder
• more naturally in context, with a little detergent powder

In laundry contexts, אבקה often means washing powder / detergent powder, even though the basic meaning is just powder.

קצת is commonly followed by a singular mass noun when you mean a little or some of something uncountable.

So:

• קצת אבקה = a little powder
• קצת מים = a little water
• קצת סוכר = a little sugar

You would not normally use the plural אבקות here, because detergent powder is being treated as an uncountable substance.

קצת מהאבקה would mean a little of the powder, which sounds more specific, as if you are talking about some particular powder already known in the conversation.

Yes, this word order is natural.

בבוקר שמתי את הסדין ואת השמיכה במכונה עם קצת אבקה is a normal sentence structure in Hebrew.

But Hebrew word order is fairly flexible, so other versions are also possible, depending on emphasis. For example:

• שמתי בבוקר את הסדין ואת השמיכה במכונה עם קצת אבקה
• את הסדין ואת השמיכה שמתי בבוקר במכונה עם קצת אבקה

The original sentence sounds neutral and straightforward.

Yes. That is exactly the idea.

The phrase עם קצת אבקה means the sheet and blanket were put into the machine, and some powder was added as part of that action.

In English, you might say:

• I put the sheet and blanket in the machine with a little detergent
• I put the sheet and blanket in the washing machine with some powder

So עם here expresses accompaniment: the machine load included some detergent powder.

A simple pronunciation guide is:

ba-bó-ker sám-ti et ha-sa-dín ve-et ha-smi-khá ba-me-kho-ná im ktzát av-ká

A few notes:

• בבוקר = baBOKer
• שמתי = SAMti
• הסדין = ha-saDIN
• השמיכה = ha-smiKHA
• במכונה = ba-mekhoNA
• אבקה = avKA

Stress in Hebrew is often on the last syllable, but not always, so it helps to learn each word individually.

Because the verb שמתי already includes the subject I.

Hebrew verbs in the past tense usually show the person, number, and sometimes gender clearly. So:

• שמתי = I put
• שמת = you put
• שם = he put
• שמה = she put

You could add אני (I) for emphasis:

• אני שמתי את הסדין... = I put the sheet...

But in a normal sentence, it is unnecessary.
