אבל הערב אני מכינה מרק חריף, כי אבא אוהב אוכל חריף.

Because the speaker is female. In Hebrew present tense, the verb agrees with the subject’s gender and number, even with אני.

• אני מכינה = said by a woman
• אני מכין = said by a man

So this sentence is being spoken by a female speaker.

Because אבא is grammatically masculine singular. Hebrew present-tense forms must match the subject.

• אבא אוהב = Dad loves
• אמא אוהבת = Mom loves

So אוהב matches אבא.

In Hebrew, adjectives usually come after the noun, not before it.

So:

• מרק חריף = spicy soup
• אוכל חריף = spicy food

This is the normal Hebrew word order for noun + adjective.

Because both מרק and אוכל are masculine singular nouns, so the adjective also appears in the masculine singular form: חריף.

If the noun changed, the adjective would change too:

• masculine singular: חריף
• feminine singular: חריפה
• masculine plural: חריפים
• feminine plural: חריפות

For example:

• מרק חריף = spicy soup
• מנה חריפה = spicy dish

Because את is used only before a definite direct object.

Here, the objects are indefinite:

• מרק חריף = a spicy soup
• אוכל חריף = spicy food / spicy food in general

So you do not use את.

Compare:

• אני מכינה מרק חריף = I’m making a spicy soup
• אני מכינה את המרק החריף = I’m making the spicy soup

Here הערב means this evening or tonight.

In Hebrew, some time expressions often appear with ה־:

• היום = today
• הלילה = tonight / the night
• הבוקר = this morning
• הערב = this evening / tonight

So אבל הערב means something like but tonight or but this evening.

This is different from בערב, which often means in the evening more generally.

Here כי means because.

So:

• כי אבא אוהב אוכל חריף = because Dad likes spicy food

Hebrew כי can sometimes have other meanings in other contexts, but in this sentence it is simply because.

When Hebrew speakers refer to a close family member such as Dad or Mom, they often use אבא and אמא almost like names.

So:

• אבא אוהב... = Dad likes...
• אמא מכינה... = Mom is making...

Using האבא would usually sound more like the father, not Dad.

In most cases, אני is useful and natural here.

Hebrew present tense shows gender and number, but it does not clearly show person the way English does. מכינה tells you the subject is feminine singular, but not automatically that it means I rather than she.

So אני helps make the subject clear:

• אני מכינה = I am making
• היא מכינה = she is making

In context, speakers sometimes omit the pronoun, but אני is very normal here.

Here אוכל is a noun, meaning food.

So:

• אוכל חריף = spicy food

This word can also be a verb form in other contexts:

• אני אוכל = I eat / I will eat (if spoken by a male, depending on context)

But in this sentence, after אוהב, it clearly means food.

Yes. It is very natural.

Hebrew word order is more flexible than English. Starting with אבל הערב puts focus on the contrast and the time:

• אבל = but
• הערב = tonight / this evening

So the sentence feels like:

• But tonight, I’m making spicy soup...

That is a very normal way to structure the sentence in Hebrew.

חריף is roughly pronounced kha-REEF or cha-REEF.

The letter ח is a guttural sound that does not exist in standard English. A common comparison is the ch in Scottish loch or German Bach.

So:

• חריף ≈ kha-REEF
• מרק חריף ≈ ma-RAK kha-REEF

Many English speakers first pronounce it like a simple h, and that is often understood, but the more authentic sound is farther back in the throat.
