Αποπαρασιτώνω τον σκύλο.

The ending -ω here tells you the verb is 1st person singular, present tense: I ...

So Αποπαρασιτώνω means I deparasite / I treat for parasites.

This is the usual dictionary form for many Modern Greek verbs, so if you look the verb up, you would normally find it under αποπαρασιτώνω.

A useful comparison:

• αποπαρασιτώνω = I deparasite
• αποπαρασιτώνεις = you deparasite
• αποπαρασιτώνει = he/she/it deparasites

Greek often leaves out the subject pronoun because the verb ending already shows who is doing the action.

Because τον σκύλο is the direct object of the verb.

In this sentence, the dog is the thing receiving the action, not the thing doing it. Greek marks that with the accusative case:

• ο σκύλος = the dog as the subject
• τον σκύλο = the dog as the object

So:

• Ο σκύλος τρέχει. = The dog runs.
• Αποπαρασιτώνω τον σκύλο. = I deparasite the dog.

This is one of the most important patterns in Greek: the article and often the noun form change depending on the noun’s role in the sentence.

This is the normal pattern for many masculine nouns ending in -ος.

For this noun:

• ο σκύλος = nominative singular
• τον σκύλο = accusative singular

So the ending changes:

• -ος → -ο

The article changes too:

• ο → τον

This is a very common pattern:

• ο άνθρωπος → τον άνθρωπο
• ο φίλος → τον φίλο
• ο δρόμος → τον δρόμο

So σκύλος / σκύλο is not irregular in any surprising way; it follows a very common masculine pattern.

Greek usually uses the definite article more often than English.

• τον σκύλο = the dog
• έναν σκύλο = a dog
• σκύλο without an article is possible in some contexts, but it is much less neutral and often sounds incomplete or stylistically marked.

So in a normal sentence, if you mean a specific dog, τον σκύλο is the natural choice.

A learner should generally expect Greek to use articles where English sometimes leaves them out.

Yes, you can, but εγώ is usually unnecessary unless you want emphasis or contrast.

Greek is a pro-drop language, which means the subject pronoun is often omitted because the verb ending already gives the subject.

So:

• Αποπαρασιτώνω τον σκύλο. = normal, neutral
• Εγώ αποπαρασιτώνω τον σκύλο. = I am deparasitizing the dog / I do it

Adding εγώ can sound like:

• emphasis
• contrast
• clarification

For example:

• Εγώ αποπαρασιτώνω τον σκύλο, όχι εσύ. = I’m deparasitizing the dog, not you.

A rough pronunciation guide is:

• Αποπαρασιτώνω ≈ a-po-pa-ra-see-TO-no
• τον ≈ ton
• σκύλο ≈ SKEE-lo

A few helpful notes:

• The stress in Αποπαρασιτώνω falls on -τώ-
• The stress in σκύλο falls on σκύ-
• υ in σκύλο is pronounced like ee
• σ is always like English s, never z
• σκ is pronounced together, like sk in skill

A more phonetic approximation: [apoparasitóno ton skílo]

Yes. The Greek present tense can often cover both:

• I deparasite the dog
• I am deparasitizing the dog

The exact meaning depends on context.

So Αποπαρασιτώνω τον σκύλο could mean:

• a general/habitual action
• what I am doing right now
• a scheduled or repeated action, depending on context

If Greek speakers want to make the ongoing meaning especially clear, context usually does the job. Greek does not divide things exactly the same way English does with simple present vs present progressive.

Yes. Greek word order is more flexible than English because case endings help show who is doing what.

The neutral order here is:

• Αποπαρασιτώνω τον σκύλο.

But you might also hear:

• Τον σκύλο αποπαρασιτώνω.
• Τον σκύλο τον αποπαρασιτώνω.

These alternatives can add emphasis, topic marking, or contrast.

For example:

• Τον σκύλο αποπαρασιτώνω, όχι τη γάτα. = It’s the dog I’m deparasitizing, not the cat.

So yes, the order can change, but the basic learner-friendly order is still verb + object here.

It is understandable and correct, but it is somewhat specialized or technical compared with very common everyday verbs.

You are likely to see or hear it in contexts such as:

• veterinary care
• pet care instructions
• medicine
• product labels
• formal or semi-formal speech about treating animals for parasites

In very everyday conversation, speakers may sometimes choose other wording depending on the situation, but αποπαρασιτώνω is a perfectly valid real verb.

So a useful learner takeaway is:

• grammatically normal
• semantically specific
• more common in pet/medical contexts than in casual small talk

σκύλος is masculine.

Yes, that matters because the article and the noun endings depend on gender and case.

Here you see:

• nominative singular masculine: ο σκύλος
• accusative singular masculine: τον σκύλο

If the noun were feminine or neuter, the forms would be different.

For example:

• τη γάτα = the cat (feminine, accusative)
• το ζώο = the animal (neuter, nominative/accusative)

So when learning nouns in Greek, it is very important to learn them with the article:

• ο σκύλος not just
• σκύλος

That helps you remember the gender and the declension pattern.

As written, τον σκύλο usually refers to a specific dog: the dog.

If you wanted a more general or indefinite meaning, Greek would normally change the wording:

• έναν σκύλο = a dog
• σκύλους = dogs
• τους σκύλους = the dogs

So:

• Αποπαρασιτώνω τον σκύλο. = a specific dog
• Αποπαρασιτώνω έναν σκύλο. = a dog
• Αποπαρασιτώνω σκύλους. = dogs

The article helps tell you whether the noun is definite or not.

In the present tense, it goes like this:

• εγώ αποπαρασιτώνω = I deparasite
• εσύ αποπαρασιτώνεις = you deparasite
• αυτός/αυτή/αυτό αποπαρασιτώνει = he/she/it deparasites
• εμείς αποπαρασιτώνουμε = we deparasite
• εσείς αποπαρασιτώνετε = you (plural/formal) deparasite
• αυτοί/αυτές/αυτά αποπαρασιτώνουν(ε) = they deparasite

This is useful because once you recognize the pattern, you can identify the subject even when the pronoun is missing.

For example:

• Αποπαρασιτώνεις τον σκύλο; = Are you deparasitizing the dog?
• Αποπαρασιτώνουμε τον σκύλο. = We deparasitize / are deparasitizing the dog.

It does more than English the.

τον tells you two things at once:

1. definiteness = the
2. case/gender/number information = masculine singular accusative

English the does not change form, but Greek articles do.

Compare:

• ο σκύλος = the dog (subject form)
• τον σκύλο = the dog (object form)

So τον is not just a translation of the; it is also a grammatical signal that helps show how the noun functions in the sentence.
