יש לי חטיף קטן בתיק, אבל בא לי לנשנש רק אחרי שנאכל.

Hebrew usually expresses to have with יש + ל־.

• יש = there is / there are
• לי = to me / for me

So יש לי חטיף קטן literally means There is to me a small snack, but in natural English that is simply I have a small snack.

This is one of the most important Hebrew patterns to get used to:

• יש לי ספר = I have a book
• יש לך זמן? = Do you have time?

Hebrew does not normally use a separate everyday verb for have the way English does.

Because חטיף is a masculine singular noun, and adjectives in Hebrew must agree with the noun in gender and number.

So:

• חטיף קטן = masculine singular
• מתנה קטנה = feminine singular
• חטיפים קטנים = masculine plural
• מתנות קטנות = feminine plural

Since חטיף is masculine, קטן must also be masculine.

בתיק means in the bag or in a bag, depending on context.

It is made of:

• ב־ = in
• תיק = bag

So:

• בתיק = in a bag / in the bag

Why can it mean both? Because Hebrew often leaves out the equivalent of the unless the context makes it clear or the noun is explicitly marked as definite.

Compare:

• בתיק = in a bag / in the bag
• בתיק שלי = in my bag
• בתיק הגדול = in the big bag

In your sentence, the natural understanding is probably in my bag or in the bag, depending on the context already known.

חטיף usually means a snack item, often something packaged, like a granola bar, chips, or some other small food.

It is not exactly the same as the general English idea of snack in every context. Often:

• חטיף = a snack food / snack bar / packaged treat
• נשנוש or לנשנש = nibbling / snacking casually

So in this sentence:

• יש לי חטיף קטן = I have a small snack item
• בא לי לנשנש = I feel like nibbling / snacking

That contrast is very natural in Hebrew.

Yes, literally בא לי looks like comes to me, but as an idiom it means:

• I feel like...
• I’m in the mood to...
• I kind of want to...

So:

• בא לי לנשנש = I feel like snacking / nibbling

This is a very common colloquial Hebrew expression.

Examples:

• בא לי קפה = I feel like having coffee
• לא בא לי לצאת = I don’t feel like going out

Even though בא is formally masculine singular, the expression בא לי is commonly used by everyone in everyday speech, including female speakers.

Because after בא לי, Hebrew normally uses an infinitive when the next idea is an action.

• לנשנש = to nibble / to snack
• לאכול = to eat
• ללכת = to go

So:

• בא לי לנשנש = I feel like snacking
• בא לי לישון = I feel like sleeping

If you said בא לי נשנש, that would be ungrammatical.

They are related, but not the same.

• לאכול = to eat in a general sense
• לנשנש = to nibble / to snack / to munch a little

לנשנש suggests small, casual eating, often between meals or not as a full meal.

So in this sentence, the speaker is saying something like:

• there is a snack available,
• they feel like munching on it,
• but only after a proper meal.

That is why לנשנש works especially well here.

In Hebrew, אחרי ש־ means after followed by a clause, roughly after (that)...

So:

• אחרי = after
• שנאכל = that we will eat / we eat

Together:

• אחרי שנאכל = after we eat

This is a very common structure:

• אחרי שנגמור = after we finish
• אחרי שתבוא = after you come
• אחרי שירד גשם = after it rains

The ש־ is a linker meaning something like that / when in these kinds of clauses.

That is normal in Hebrew. After words like אחרי ש־ (after), Hebrew often uses the future form to refer to an action that will happen before another future-related action.

So:

• אחרי שנאכל literally looks like after we will eat
• but in natural English it becomes after we eat

This is very common and not weird in Hebrew.

For example:

• נדבר אחרי שתחזור = We’ll talk after you come back
• אלך לישון אחרי שאסיים = I’ll go to sleep after I finish

So the future form here is exactly what you would expect in Hebrew.

In this sentence, נאכל means we will eat / we eat from the verb לאכול (to eat).

Context makes that clear:

• אחרי שנאכל = after we eat

There is another verb pattern where a very similar-looking form can mean be eaten, but that is not what is happening here. In this sentence, the meaning is active and straightforward: we eat.

A learner should mainly recognize נאכל here as first person plural future:

• אני אוכל / אני אוכלֶת = I eat
• אנחנו נאכל = we will eat

Because Hebrew, like English, can leave the object unstated when it is obvious from context.

So אחרי שנאכל means:

• after we eat
• more naturally, after we have our meal

You do not need to say אחרי שנאכל ארוחה unless you specifically want to emphasize a meal.

English does this too:

• Let’s talk after we eat. You do not have to say after we eat dinner unless that detail matters.

אבל means but.

It connects two contrasting ideas:

• יש לי חטיף קטן בתיק = I have a small snack in my bag
• אבל בא לי לנשנש רק אחרי שנאכל = but I only feel like snacking after we eat

So the contrast is:

• the snack is available now,
• but the speaker does not want to eat it yet.

רק means only, and here it limits the time:

• בא לי לנשנש רק אחרי שנאכל = I feel like snacking only after we eat

That means not before.

If you move רק, the emphasis can shift. Hebrew word order is somewhat flexible, but in this sentence the placement is very natural because it clearly means:

• the snacking should happen only after the meal

It is mostly everyday, natural spoken Hebrew.

Especially colloquial elements:

• בא לי = very common spoken way to say I feel like
• לנשנש = casual, everyday verb for snack / nibble

The sentence sounds natural in conversation. It is not slangy in a strange way, but it is definitely more conversational than formal written Hebrew.
