אין מספיק אבקה בבית, ולכן אני לא שמה את השמיכה במכונה היום.

אין is the normal Hebrew way to say that something does not exist / there isn’t.

So:

אין מספיק אבקה בבית = There isn’t enough detergent/powder at home

Hebrew does not usually say לא יש for there isn’t.
Instead, the pair is:

• יש = there is / there are
• אין = there isn’t / there aren’t

So this part is about existence or availability, not just plain negation.

Great question. In this kind of sentence, מספיק often works like a quantity word meaning enough, and in everyday Hebrew it is very commonly left in the default masculine singular form, even before feminine or plural nouns.

So speakers naturally say:

• מספיק זמן = enough time
• מספיק כסף = enough money
• מספיק אבקה = enough detergent/powder

If מספיק were being used more clearly as a regular adjective after the noun, agreement would be more visible:

• האבקה מספיקה = the powder/detergent is sufficient

So here, מספיק is behaving more like enough as a quantity marker than like a fully agreeing adjective.

Literally, אבקה means powder. But in this context, because the sentence is about washing a blanket, it most naturally means laundry detergent powder or just detergent.

So while the word by itself can mean powder in a general sense, context tells you what kind of powder is meant.

Hebrew prepositions like ב = in / at attach directly to the following word, so בבית is one written word.

This form can mean different things depending on context:

• in a house
• in the house
• at home

In unpointed modern Hebrew, these are often spelled the same way: בבית.

Here, the natural meaning is at home or in the house.

So:

אין מספיק אבקה בבית = There isn’t enough detergent at home

ולכן means and therefore, and so, or therefore.

It is made of:

• ו = and
• לכן = therefore

So:

ולכן אני לא שמה... = and therefore / so I’m not putting...

Compared with אז:

• אז is often more conversational and can mean so, then, or well
• ולכן sounds a bit more explicit and logical: therefore / as a result

Both can sometimes fit, but ולכן clearly marks cause and result.

Yes. שמה is the feminine singular present-tense form of the verb לשים = to put.

So:

• אני לא שם = I am not putting ... — said by a male speaker
• אני לא שמה = I am not putting ... — said by a female speaker

Hebrew present tense agrees with the gender and number of the subject, even with אני.

So this sentence tells you the speaker is female.

It can look confusing, but here שמה is from the verb לשים = to put.

So in this sentence:

אני לא שמה את השמיכה... = I’m not putting the blanket...

It is not the word שם meaning there.

This is a very common source of confusion because Hebrew spelling often leaves out vowels, so forms that look similar can belong to completely different words.

את here is the direct object marker. It is used before a definite direct object.

So:

• אני שמה שמיכה = I’m putting a blanket
• אני שמה את השמיכה = I’m putting the blanket

In English, we usually do not have a separate word for this, so את is often left untranslated.

A good way to think of it is:

• if the direct object is specific/definite, Hebrew often uses את
• if it is indefinite, it usually does not

השמיכה means the blanket, while שמיכה means a blanket.

The sentence uses השמיכה because it is talking about a specific blanket, not just any blanket.

That is also why the sentence needs את before it:

• את השמיכה = the blanket as a definite direct object

So the speaker has a particular blanket in mind.

במכונה means in the machine or into the machine, depending on context.

With a verb like לשים = to put, Hebrew often uses ב when something is being placed inside something:

• לשים את הספר בתיק = put the book in the bag
• לשים את הכביסה במכונה = put the laundry in the machine

Using ל would sound more like to/toward the machine, not inside the machine.

As for מכונה, in this context it clearly means the washing machine, even though the full phrase would be מכונת כביסה. In everyday speech, Hebrew often shortens it to just מכונה when the context is laundry.

Yes, היום is flexible. Hebrew allows adverbs of time to move around more than English sometimes does.

This sentence says:

אני לא שמה את השמיכה במכונה היום
= I’m not putting the blanket in the machine today

Putting היום at the end sounds very natural and gives a slight focus to today.

Other possible word orders include:

• היום אני לא שמה את השמיכה במכונה
• אני היום לא שמה את השמיכה במכונה

These are all possible, but the version with היום at the end is very idiomatic and smooth.
