Μετά το ραντεβού, η ασθενής πήγε στο φαρμακείο.

Because μετά changes meaning depending on the case that follows it.

• μετά + accusative = after
• μετά + genitive = with (mainly formal/literary in Modern Greek)

In Μετά το ραντεβού, the noun phrase is in the accusative, so the meaning is after the appointment.

Ραντεβού is a neuter noun, so in the singular it takes the neuter article:

• το ραντεβού = the appointment

A useful thing to know is that ραντεβού is largely indeclinable in Modern Greek. That means the noun itself usually stays the same, while the article shows the case:

• nominative: το ραντεβού
• accusative: το ραντεβού
• genitive: του ραντεβού

So in this sentence, the form ραντεβού does not change.

It means the patient, specifically a female patient.

• η = feminine singular definite article
• ασθενής = patient

So:

• η ασθενής = the female patient
• ο ασθενής = the male patient

The article tells you the gender here.

It is originally an adjective meaning sick, ill, or weak, but it is very commonly used as a noun to mean patient.

So Greek can use it like this:

• ασθενής άνθρωπος = a sick person
• η ασθενής = the patient

This is very common in Greek: an adjective can function as a noun when the context is clear.

Πήγε is the aorist form of πηγαίνω and means went as a completed action.

• πήγε = went
• πήγαινε can mean was going / used to go (imperfect), depending on context

In this sentence, the person completed one action: she went to the pharmacy after the appointment. That is why Greek uses the aorist.

It comes from πηγαίνω, which means to go.

This verb has an irregular past form:

• present: πηγαίνω = I go / am going
• aorist: πήγα = I went
• 3rd person singular aorist: πήγε = he/she/it went

So η ασθενής πήγε means the patient went.

Because στο is the normal contraction of:

• σε + το = στο

This is extremely common in Modern Greek.

Other common contractions are:

• σε + τον = στον
• σε + την = στην / στη
• σε + τις = στις
• σε + τους = στους

So:

• στο φαρμακείο = to the pharmacy / at the pharmacy, depending on context

It is in the accusative, because after σε / στο Modern Greek normally uses the accusative.

So:

• στο φαρμακείο = to the pharmacy / at the pharmacy

The form happens to look the same as the nominative because φαρμακείο is a neuter noun:

• nominative: το φαρμακείο
• accusative: το φαρμακείο

Again, the article helps show the structure.

It can mean either one in Greek, depending on the verb and context.

• with a verb of motion like πήγε (went), it means to the pharmacy
• with a verb of location like είναι (is), it means at the pharmacy

So here:

• πήγε στο φαρμακείο = went to the pharmacy

Yes, both are possible, but they mean slightly different things.

• στο φαρμακείο = to the pharmacy / to the specific pharmacy
• σε φαρμακείο = to a pharmacy / to some pharmacy

Greek uses the definite article very often, and in many everyday situations it sounds natural to say στο φαρμακείο, even when English might simply say to the pharmacy without strongly emphasizing which one.

Because Μετά το ραντεβού is an introductory time phrase: After the appointment.

Greek often puts a comma after an introductory phrase, especially when it comes at the beginning of the sentence. It helps separate the time setting from the main clause:

• Μετά το ραντεβού, η ασθενής πήγε στο φαρμακείο.

You may also see Greek sentences without such a comma in more casual writing, but here it is perfectly natural.

Yes. Greek word order is more flexible than English because the articles and verb forms carry a lot of grammatical information.

For example, these are all possible:

• Μετά το ραντεβού, η ασθενής πήγε στο φαρμακείο.
• Η ασθενής πήγε στο φαρμακείο μετά το ραντεβού.
• Στο φαρμακείο πήγε η ασθενής μετά το ραντεβού.

They all express roughly the same basic meaning, but the emphasis changes. The original sentence puts the time phrase first, which feels natural for setting the scene.

A rough English-style pronunciation would be:

meh-TA to ran-deh-VOO, ee as-theh-NEES PEE-ye sto far-mah-kee-O

A few helpful notes:

• η is pronounced like ee
• γ before ε or ι often sounds like a soft y sound, so πήγε sounds like PEE-ye
• ει in φαρμακείο sounds like ee
• Greek stress matters a lot, so pay attention to the accented syllables:
  • μετά
  • ραντεβού
  • ασθενής
  • πήγε
  • φαρμακείο

Yes. Greek usually does not need subject pronouns like he, she, or they if the verb form and context already make the subject clear.

Here:

• πήγε = went (3rd person singular)
• η ασθενής already tells us who did the action

So Greek does not need an extra pronoun like αυτή. Adding it would usually give extra emphasis:

• Η ασθενής πήγε = The patient went
• Η ασθενής αυτή πήγε or Αυτή πήγε = more emphatic, like she is the one who went

No. It is a loanword, originally from French rendez-vous.

Modern Greek uses many loanwords in everyday speech, and ραντεβού is one of the most common. Even though it comes from another language, it behaves like a normal Greek noun in a sentence, especially through its article:

• το ραντεβού
• μετά το ραντεβού
• του ραντεβού

So it is very common and completely natural Greek.
