Ο αρραβωνιαστικός της δεν θέλει μεγάλη δεξίωση, γιατί προτιμά να καλέσει μόνο λίγους φίλους.

It means her fiancé or her betrothed.

• ο αρραβωνιαστικός = the fiancé / the engaged man
• της = her

So literally it is the fiancé of hers.

In Greek, possessive pronouns like μου, σου, του, της, μας, σας, τους often come after the noun.

So:

• ο φίλος μου = my friend
• η αδελφή της = her sister
• ο αρραβωνιαστικός της = her fiancé

This is a very normal Greek structure.

δεν is the standard negation used before verbs in statements.

• θέλει = he/she wants
• δεν θέλει = he/she does not want

So δεν θέλει μεγάλη δεξίωση means he doesn’t want a big reception.

Greek does not have a separate indefinite article like English a/an.

So:

• δεξίωση can mean a reception
• μεγάλη δεξίωση can mean a big reception

Greek often leaves the noun without an article when the meaning is indefinite.

Because both words must agree in gender, number, and case.

Here, δεξίωση is:

• feminine
• singular
• accusative

So the adjective must match:

• μεγάλη δεξίωση = a big reception

This whole phrase is the object of θέλει.

Yes, γιατί can mean both because and why.

In this sentence, it means because:

• ..., γιατί προτιμά... = ..., because he prefers...

When it means why, it is usually part of a question:

• Γιατί έφυγε; = Why did he leave?

So you understand the meaning from context and punctuation.

Modern Greek usually does not use an infinitive the way English does.

Instead, Greek uses:

• να + verb

So:

• προτιμά να καλέσει = he prefers to invite

This pattern is extremely common:

• θέλω να πάω = I want to go
• μπορώ να έρθω = I can come
• προτιμώ να μείνω = I prefer to stay

Because after να, Greek often chooses between a present and an aorist form depending on meaning.

• να καλεί would suggest repeated or ongoing inviting
• να καλέσει presents the action as a single complete event: to invite

Here, inviting the friends is seen as one whole action, so να καλέσει is the natural choice.

It is accusative plural masculine, because it is the object of καλέσει.

• φίλοι = friends (nominative plural)
• φίλους = friends (accusative plural)

And λίγους matches φίλους:

• masculine
• plural
• accusative

So:

• μόνο λίγους φίλους = only a few friends

μόνο means only.

It limits what follows:

• μόνο λίγους φίλους = only a few friends

So the idea is that he prefers inviting a small number of friends, not lots of people.

The subject is still ο αρραβωνιαστικός της.

Greek often does not repeat the subject pronoun if it is already clear from context.

So the sentence means:

• Her fiancé doesn’t want a big reception, because he prefers to invite only a few friends.

Greek does not need to repeat he.

Yes:

• Ο αρραβωνιαστικός = nominative singular masculine
  
  • the subject
• της = genitive
  
  • her / of her
• μεγάλη δεξίωση = accusative singular feminine
  
  • object of θέλει
• λίγους φίλους = accusative plural masculine
  
  • object of καλέσει

So the sentence is a good example of how Greek uses endings to show each word’s role.

No, Greek word order is more flexible than English word order, although this sentence uses a very natural, standard order.

Current order:

• Ο αρραβωνιαστικός της = subject
• δεν θέλει = verb
• μεγάλη δεξίωση = object
• γιατί... = reason clause

The sentence sounds natural as written, but Greek can move parts around for emphasis. For example, μόνο is placed right before λίγους φίλους to emphasize only a few friends.

Here δεξίωση means reception, especially a formal social gathering, such as a wedding reception or engagement-related event.

So μεγάλη δεξίωση suggests a fairly large formal celebration, not just a casual party.

Usually it means fiancé or engaged man, so yes, it normally refers to someone who is engaged to be married.

It is related to:

• αρραβώνας = engagement
• αρραβωνιαστικιά = fiancée

So ο αρραβωνιαστικός της is specifically her fiancé, not just her boyfriend.
