Ο φαρμακοποιός μου έδωσε αλοιφή για την πληγή και έναν επίδεσμο για το γόνατο.

μου means to me or my, depending on context. In this sentence, it means to me:

Ο φαρμακοποιός μου έδωσε... = The pharmacist gave me...

Greek often uses a short unstressed pronoun like μου before the verb instead of a fuller phrase such as σε μένα.

So:

• μου έδωσε = gave me
• literally, it is something like to-me gave

This is very common in Greek with indirect objects:

• μου = to me
• σου = to you
• του / της = to him / her

Because μου is a weak pronoun, and in normal Modern Greek it usually comes before a finite verb:

• μου έδωσε = he/she gave me
• σου λέω = I tell you
• του μίλησα = I spoke to him

So Ο φαρμακοποιός μου έδωσε... is the normal word order.

You may sometimes hear different placement in special contexts, but for everyday standard Greek, learners should think of μου as normally going before the verb.

Greek does not always use the indefinite article the same way English uses a/an.

Here:

• αλοιφή = ointment
• έναν επίδεσμο = a bandage

With substances, materials, or uncountable things, Greek often leaves out the indefinite article. Αλοιφή is being treated like an uncountable medical substance, so no article is needed.

By contrast, επίδεσμος is a countable object, so έναν is natural:

• έναν επίδεσμο = a bandage

So the contrast is very natural:

• αλοιφή = ointment
• έναν επίδεσμο = a bandage

Because επίδεσμο is the direct object of the verb έδωσε.

The basic form is:

• ένας επίδεσμος = a bandage

But after the verb, as the thing being given, it must go into the accusative case:

• έναν επίδεσμο = a bandage

So:

• ένας επίδεσμος = nominative, subject form
• έναν επίδεσμο = accusative, object form

Greek marks this change clearly in masculine nouns and articles.

These are also in the accusative, because they come after the preposition για.

• η πληγή = the wound
• την πληγή = the wound, after για
• το γόνατο = the knee

γόνατο is neuter, and neuter nominative and accusative are the same, so το γόνατο does not change form.

So:

• για την πληγή = for the wound
• για το γόνατο = for the knee

In this sentence, για means for.

• αλοιφή για την πληγή = ointment for the wound
• έναν επίδεσμο για το γόνατο = a bandage for the knee

It shows purpose or intended use.

This is different from some other meanings of για, because για is a very flexible preposition in Greek. Depending on context, it can also mean things like:

• for
• about
• intended for
• because of
• during a period of time

But here the meaning is simply for / intended for.

Literally it means for the knee, but naturally it means for use on the knee.

Greek often uses a body part directly in this way, just as English can say:

• a brace for the knee
• cream for the skin
• drops for the eyes

So έναν επίδεσμο για το γόνατο does not mean the bandage is somehow being given to the knee. It means it is meant to be used on or for the knee.

Yes, Greek often can leave out subject pronouns like he/she, because the verb ending already gives information about the subject.

But here Ο φαρμακοποιός is not a pronoun; it is the full noun phrase the pharmacist. It is included because the sentence wants to say specifically who gave the items.

• Ο φαρμακοποιός μου έδωσε... = The pharmacist gave me...

If the context already made the subject obvious, Greek could sometimes omit it and just say:

• Μου έδωσε αλοιφή... = He/She gave me ointment...

But including Ο φαρμακοποιός makes the sentence explicit and clear.

Yes. φαρμακοποιός is a masculine noun here, and ο φαρμακοποιός means the pharmacist.

Its ending -ός is a common masculine pattern in Greek. In this sentence it is the subject, so it is in the nominative:

• ο φαρμακοποιός = the pharmacist

You may notice the stress mark stays on the final syllable:

• φαρμακοποιός

This is just the normal dictionary form of the word.

Here και is just the normal word and. It connects the two things the pharmacist gave:

• αλοιφή για την πληγή
• έναν επίδεσμο για το γόνατο

So the structure is:

μου έδωσε

• αλοιφή για την πληγή
• και
• έναν επίδεσμο για το γόνατο

In other words: he gave me two items.

Yes, that is a very good way to understand it.

The structure is:

• Ο φαρμακοποιός = subject
• μου έδωσε = gave me
• αλοιφή για την πληγή = item 1
• και έναν επίδεσμο για το γόνατο = item 2

So a natural breakdown is:

The pharmacist + gave me + ointment for the wound + and + a bandage for the knee

That is a very useful way to process the sentence.

Yes. έδωσε is the simple past form of δίνω (to give).

So:

• δίνει = he/she gives
• έδωσε = he/she gave

In this sentence:

• Ο φαρμακοποιός μου έδωσε... = The pharmacist gave me...

This is the common Greek past tense form often called the aorist.

Yes, that is very important.

Greek nouns have gender, and the article helps you remember it:

• ο φαρμακοποιός = masculine
• η πληγή = feminine
• το γόνατο = neuter
• ο επίδεσμος = masculine
• η αλοιφή = feminine

If you learn the noun with its article, it becomes much easier to form correct phrases later:

• την πληγή
• έναν επίδεσμο
• το γόνατο

This is one of the best habits for learning Greek vocabulary.
