Το τσίμπημα από κουνούπι πονάει λίγο, αλλά δεν είναι σοβαρό.

Το is the neuter singular definite article, meaning the.

So:

• τσίμπημα = bite / sting
• το τσίμπημα = the bite / the sting

Greek often uses the article where English might or might not use the, depending on context. In this sentence, το τσίμπημα refers to the bite being discussed, so the mosquito bite is natural.

Also, τσίμπημα is a neuter noun, which is why the article is το.

Τσίμπημα means bite or sting, depending on the context.

With κουνούπι (mosquito), it means mosquito bite.

This is very common in Greek: the noun τσίμπημα can be used for insects that technically bite or sting in English. Greek does not always divide those as strictly as English does.

It comes from the verb:

• τσιμπάω / τσιμπώ = to bite, sting, pinch

And the ending -μα often makes a noun showing the result of an action:

• τσιμπάω → τσίμπημα
• roughly: to bite/sting → a bite/sting

Yes, από literally means from, but here it is used in a very natural Greek way to mean caused by or coming from.

So:

• τσίμπημα από κουνούπι = a bite from a mosquito / a mosquito bite

This is a common pattern in Greek:

• πόνος από το δόντι = pain from the tooth
• τραύμα από ατύχημα = injury from an accident

So even though English may prefer mosquito bite, Greek often uses noun + από + cause/source.

Because κουνούπι here is being used in a general, indefinite way: from a mosquito rather than from the mosquito.

Compare:

• από κουνούπι = from a mosquito / mosquito-related
• από το κουνούπι = from the mosquito (a specific mosquito already known in the conversation)

In this sentence, Greek is talking generally about the kind of bite, not one specific mosquito, so από κουνούπι sounds natural.

Yes. That is also correct and very natural.

Two common ways to say mosquito bite are:

• το τσίμπημα από κουνούπι
• το τσίμπημα κουνουπιού

The second one uses the genitive:

• κουνούπι = mosquito
• κουνουπιού = of a mosquito

So literally:

• το τσίμπημα κουνουπιού = the bite of a mosquito

Both are good.
A learner may hear either one.

Very roughly:

• από κουνούπι emphasizes source/cause
• κουνουπιού is a tighter noun phrase, like mosquito bite

Κουνούπι is a neuter singular noun meaning mosquito.

Its basic forms are:

• το κουνούπι = nominative / accusative singular
• του κουνουπιού = genitive singular
• τα κουνούπια = nominative / accusative plural
• των κουνουπιών = genitive plural

In this sentence, after από, you see κουνούπι in the same form as the basic singular.

Πονάει means it hurts.

The verb is:

• πονάω / πονώ = to hurt, ache

For he/she/it hurts, you can commonly hear:

• πονάει
• πονά

Both are used in modern Greek.

Here, the subject is το τσίμπημα, which is singular and neuter, so Greek uses it hurts:

• Το τσίμπημα πονάει = The bite hurts

Yes.

Both are standard in Modern Greek:

• πονάει
• πονά

So these both work:

• Το τσίμπημα πονάει λίγο.
• Το τσίμπημα πονά λίγο.

The version with -άει is very common in everyday speech and writing.

Here λίγο means a little and works as an adverb, modifying the verb πονάει.

So:

• πονάει λίγο = it hurts a little

That is different from using λίγος / λίγη / λίγο as an adjective meaning little / small amount of before a noun.

Examples:

• Πονάει λίγο. = It hurts a little.
• λίγο νερό = a little water

In this sentence, it is not describing the bite itself. It is describing the degree of pain.

Because σοβαρό must agree with το τσίμπημα, which is neuter singular.

Greek adjectives agree with the noun they describe in gender and number.

So:

• σοβαρός = masculine
• σοβαρή = feminine
• σοβαρό = neuter

Since the subject is:

• το τσίμπημα = neuter singular

the sentence says:

• δεν είναι σοβαρό = it is not serious

Because Greek needs the verb είναι (is) in this kind of sentence.

So:

• είναι σοβαρό = it is serious
• δεν είναι σοβαρό = it is not serious

Δεν is the normal negation used before verbs in Modern Greek.

So the pattern is:

• δεν + verb

Examples:

• δεν πονάει = it doesn’t hurt
• δεν είναι σοβαρό = it isn’t serious

Αλλά means but.

It connects two contrasting ideas:

• Το τσίμπημα από κουνούπι πονάει λίγο = The mosquito bite hurts a little
• αλλά δεν είναι σοβαρό = but it isn’t serious

So the sentence means: there is some pain, but it is not dangerous or important.

Yes. It is normal to put a comma before αλλά when it links two clauses, just like English often uses a comma before but.

So:

• ..., αλλά ...

is standard punctuation here.

Yes, that is very normal in Greek.

Greek often uses:

• τσιμπάω
• τσίμπημα

for insect bites and stings generally.

So depending on the animal or insect, English may choose:

• bite
• sting

but Greek may still use τσίμπημα.

With κουνούπι, the natural English translation is mosquito bite.

Usually no, not naturally.

Δάγκωμα comes from δαγκώνω (to bite) and is more appropriate for things like:

• a dog bite
• a human bite
• an animal bite

For insects like mosquitoes, τσίμπημα is the normal word.

So:

• τσίμπημα από κουνούπι = natural
• δάγκωμα από κουνούπι = not the usual choice

A simple pronunciation guide is:

To TSIM-bi-ma a-PO kou-NOU-pi po-NA-i LI-go, a-LA den I-ne so-va-RO.

A few stress points:

• τσίμπημα → stress on τσί-
• από → stress on -πό
• κουνούπι → stress on -νού-
• πονάει → stress on -νά-
• λίγο → stress on λί-
• αλλά → stress on -λά
• σοβαρό → stress on -ρό

Also:

• τσ sounds like ts in cats
• μπ here sounds like b
• ου sounds like oo in food

Yes, Greek word order is more flexible than English, though not completely free.

The neutral order here is:

• Το τσίμπημα από κουνούπι πονάει λίγο, αλλά δεν είναι σοβαρό.

But you may also hear things like:

• Πονάει λίγο το τσίμπημα από κουνούπι, αλλά δεν είναι σοβαρό.

That can sound more marked, with slightly different emphasis.
The original version is the most straightforward and natural for a learner to use.

No, and that is completely normal.

In:

• Το τσίμπημα από κουνούπι πονάει λίγο, αλλά δεν είναι σοβαρό.

the subject το τσίμπημα από κουνούπι is understood to continue into the second clause.

So Greek does not need to repeat:

• αλλά το τσίμπημα δεν είναι σοβαρό

It could be repeated for emphasis or clarity, but normally it is omitted because the meaning is already clear.

Yes, it is natural, standard, everyday Greek.

Nothing in it is unusually formal, literary, or slangy.

A Greek speaker could naturally say this in normal conversation, for example when reassuring someone about an insect bite.
