Ο αντίπαλος όντως μπλοφάρει.

ο is the masculine singular definite article, meaning the.

So:

• ο αντίπαλος = the opponent

In Greek, the definite article is used very regularly with nouns, much more than in English in some situations. Here, if you are talking about a specific opponent, ο αντίπαλος is the normal choice.

A few related forms are:

• ο = masculine singular nominative
• η = feminine singular nominative
• το = neuter singular nominative

So this sentence is specifically talking about the opponent, not just an opponent.

αντίπαλος is in the nominative singular.

You can tell because:

• it is the subject of the sentence
• it appears with the nominative article ο

So:

• ο αντίπαλος = the opponent as the subject

If the word were in another case, the article would change. For example:

• τον αντίπαλο = the opponent (object)

In this sentence, the opponent is the one doing the action, so nominative is exactly what you expect.

Not necessarily in real-world meaning, but in this sentence it is marked as masculine because of the article ο.

Greek often shows grammatical gender through the article. With αντίπαλος, the form of the noun itself can stay the same, while the article changes:

• ο αντίπαλος = the male opponent / the opponent (masculine)
• η αντίπαλος = the female opponent

So the article is doing important work here. If the speaker meant a female opponent, they would normally say Η αντίπαλος όντως μπλοφάρει.

όντως adds the idea of indeed, really, or actually.

So it strengthens or confirms the statement:

• Ο αντίπαλος μπλοφάρει. = The opponent is bluffing.
• Ο αντίπαλος όντως μπλοφάρει. = The opponent really is bluffing. / The opponent is indeed bluffing.

It often sounds like the speaker is confirming something that may have been doubtful before.

A useful nuance:

• όντως often has a sense of in fact / truly
• it can sound a bit more confirming than a plain really

Because Greek does not need a separate verb like English is to form the present progressive.

μπλοφάρει is the present tense, 3rd person singular of μπλοφάρω. In context, Greek present tense can mean:

• bluffs
• is bluffing

So:

• Ο αντίπαλος μπλοφάρει can mean The opponent bluffs or The opponent is bluffing

In this sentence, English usually sounds more natural with is bluffing, especially if you are describing what is happening now.

The dictionary form is μπλοφάρω.

That is the 1st person singular form used as the citation form for many Modern Greek verbs:

• μπλοφάρω = I bluff
• μπλοφάρεις = you bluff
• μπλοφάρει = he/she/it bluffs, is bluffing

This verb is a loan-based Greek verb built from the idea of bluff and adapted to Greek verb patterns.

Yes. It is completely normal Greek usage.

Modern Greek has many verbs that come from foreign roots and are adapted into Greek, often with endings like -άρω. So μπλοφάρω behaves like a regular Greek verb in everyday language.

That means learners should treat it as a real Greek verb grammatically, even if its origin is not originally Greek.

In Modern Greek, μπ is commonly used to represent a b sound, especially in words like this one.

So μπλοφάρει begins roughly like:

• blo-

A simple pronunciation guide for the whole word is approximately:

• blo-FA-ri

with the stress on φά.

So the sentence begins approximately like:

• o an-DI-pa-los ON-dos blo-FA-ri

That is only an approximation for English speakers, but it is a helpful start.

Yes, Greek word order is flexible, and όντως can move depending on emphasis.

The given order is very natural:

• Ο αντίπαλος όντως μπλοφάρει.

It presents the subject first, then the confirming adverb, then the verb.

But you may also hear:

• Ο αντίπαλος μπλοφάρει όντως.
• Όντως ο αντίπαλος μπλοφάρει.

These are not all identical in emphasis.

Very roughly:

• Ο αντίπαλος όντως μπλοφάρει = neutral, natural
• Όντως ο αντίπαλος μπλοφάρει = stronger focus on indeed / actually
• Ο αντίπαλος μπλοφάρει όντως = possible, but often less neutral depending on context

For a learner, the original order is an excellent standard pattern to remember.

Greek often leaves out subject pronouns when they are not needed. This is because the verb ending already gives person and number information.

Here, μπλοφάρει already tells you the verb is 3rd person singular. And the subject is explicitly given as ο αντίπαλος, so adding a pronoun would be unnecessary.

Greek does this all the time. Compare:

• Μπλοφάρει. = He/She is bluffing.
• Ο αντίπαλος μπλοφάρει. = The opponent is bluffing.

Since the noun subject is already present, no pronoun is needed.

They overlap, but they are not always identical.

• όντως = indeed, actually, truly
• πραγματικά = really, genuinely, truly
• αλήθεια can mean truly, but very often it also means truth or is used in expressions

In this sentence, όντως sounds like the speaker is confirming a fact:

• Ο αντίπαλος όντως μπλοφάρει.
  = The opponent really is bluffing.

If you said:

• Ο αντίπαλος πραγματικά μπλοφάρει

that can also work, but the nuance may feel slightly different depending on context. For this kind of confirmation, όντως is a very natural choice.

Yes, stress matters in Greek and is shown in writing.

In this sentence:

• Ο — no stress mark
• αντίπαλος — stress on τί
• όντως — stress on ό
• μπλοφάρει — stress on φά

So the stressed syllables are:

• ανΤΙπαλος
• ΟΝτως
• μπλοΦΑρει

Stress is important because it is part of the correct pronunciation, and in some cases stress can distinguish different words or forms. Greek spelling helps you by marking it clearly with an accent.
