Ο συμπαίκτης μου μάντεψε τη λέξη από την υπόδειξη.

In Greek, a specific noun usually takes the definite article. So:

• ο συμπαίκτης μου = my teammate
• literally: the teammate of me

This is very normal Greek structure. English often drops the before possessives, but Greek usually keeps the article:

• ο φίλος μου = my friend
• η αδερφή μου = my sister

Here ο is the masculine singular nominative article because συμπαίκτης is masculine and is the subject of the sentence.

Συμπαίκτης means teammate, fellow player, or co-player, depending on context.

It is built from:

• συν-/συμ- = with, together
• παίκτης = player

So the word literally suggests someone who plays with you.

That is the normal Greek pattern for unstressed possessives:

• ο συμπαίκτης μου = my teammate
• το βιβλίο μου = my book
• η ιδέα μου = my idea

So Greek commonly uses:

• article + noun + possessive pronoun

The word μου here is an unstressed genitive pronoun meaning my.

Μάντεψε is the aorist form, which here works like the simple past in English: guessed.

It is:

• 3rd person singular
• from the verb μαντεύω = to guess

So:

• μαντεύει = he/she guesses, is guessing
• μάντεψε = he/she guessed

Greek does not need an extra word like did here. The verb form itself already shows past time.

Because λέξη is the direct object of the verb μάντεψε.

Compare:

• η λέξη = the word as a subject
• τη λέξη or την λέξη = the word as an object

In this sentence, the teammate is doing the action, and the word is what was guessed, so Greek uses the accusative:

• Ο συμπαίκτης μου μάντεψε τη λέξη.

The noun λέξη itself stays the same here, but the article changes from η to τη(ν).

This is about the final -ν in the feminine accusative article την.

Before some sounds, Greek often drops that -ν:

• τη λέξη

But before a vowel, Greek keeps it:

• την υπόδειξη

Since υπόδειξη begins with a vowel sound, την is the expected form.

So:

• τη λέξη = normal before λ
• την υπόδειξη = normal before a vowel

It is in the accusative.

In Modern Greek, most common prepositions take the accusative, including από.

So:

• από την υπόδειξη = from the clue/hint

Even though English learners may expect something like a different case after from, Modern Greek uses the accusative here.

Yes, but in this sentence it means more like from, based on, or using as the source.

So μάντεψε τη λέξη από την υπόδειξη means the person got the word from the hint/clue.

This use is very natural in Greek when talking about the source of information or the basis for a guess.

Not always exactly.

Υπόδειξη can mean:

• hint
• clue
• indication
• sometimes even suggestion, depending on context

In a game or puzzle context, translating it as clue or hint is very natural. So in this sentence, υπόδειξη is the piece of information that helped the teammate guess the word.

The given order is natural and straightforward:

• Ο συμπαίκτης μου μάντεψε τη λέξη από την υπόδειξη.

Greek word order is more flexible than English because articles and case endings help show each word’s role.

You could move parts around for emphasis, for example:

• Από την υπόδειξη ο συμπαίκτης μου μάντεψε τη λέξη.

That would put more focus on from the clue.

Still, the original version is probably the most neutral and easiest for learners to understand.

Greek gives you clues through the articles and forms.

In this sentence:

• ο συμπαίκτης μου is the subject
  
  • ο shows masculine nominative singular
• τη λέξη is the direct object
  
  • τη shows feminine accusative singular

So even if English relies heavily on word order, Greek often makes this clearer through case marking.

That is why:

• ο συμπαίκτης μου = the one who did the guessing
• τη λέξη = the thing that was guessed
