Ο αρχηγός μιλάει τώρα.

Ο is the masculine singular definite article, meaning the.

So:

• ο αρχηγός = the leader / the chief / the captain

In Greek, nouns usually appear with their article more often than in English, especially when talking about a specific person.

Αρχηγός usually means leader, chief, head, or sometimes captain, depending on context.

For example, it could refer to:

• the leader of a group
• the head of a political party
• a team captain
• a chief or boss

So the exact English word can change a little depending on the situation.

The ending -ός is a very common masculine noun ending in Greek.

Here, αρχηγός is in the nominative singular, which is the form used for the subject of the sentence.

In this sentence, ο αρχηγός is the subject, so nominative is exactly what you expect.

Yes. Although ο αρχηγός here is masculine, the noun αρχηγός can also be used for a female leader with the feminine article:

• η αρχηγός = the female leader

So the noun itself may stay the same, while the article changes.

Μιλάει is the 3rd person singular present tense of μιλάω / μιλώ, meaning to speak / to talk.

So μιλάει means:

• he speaks
• she speaks
• it speaks
• and in context often he/she is speaking

Because the subject is ο αρχηγός, here it means the leader speaks / is speaking.

In Modern Greek, the present tense often covers both the simple present and the present continuous.

So:

• μιλάει can mean speaks
• μιλάει can also mean is speaking

English makes a stronger distinction here than Greek does.

So depending on context, the sentence could be understood as either:

• The leader speaks now
• The leader is speaking now

With τώρα, the continuous idea is speaking now is often the most natural in English.

Both are used.

You may see:

• μιλάει
• μιλά

Both can mean he/she is speaking.

Μιλάει is very common and often feels a bit fuller or clearer to learners.
Μιλά is also completely normal in Modern Greek.

So you should recognize both.

Τώρα means now.

It tells you the action is happening at the present moment:

• Ο αρχηγός μιλάει τώρα. = The leader is speaking now.

It can also help make the sentence sound more immediate.

No. Greek word order is fairly flexible.

You could also hear:

• Τώρα ο αρχηγός μιλάει.
• Ο αρχηγός τώρα μιλάει.

These are all possible, though they may sound slightly different in emphasis.

• Ο αρχηγός μιλάει τώρα is a straightforward neutral sentence.
• Τώρα ο αρχηγός μιλάει puts more focus on now.
• Ο αρχηγός τώρα μιλάει can also emphasize the timing.

Usually, no.

Greek often drops subject pronouns because the verb ending already gives that information.

For example:

• μιλάω = I speak
• μιλάς = you speak
• μιλάει = he/she/it speaks

So Greek does not need a separate word for he here.

In this sentence, the subject is explicitly stated as ο αρχηγός, so a pronoun would be unnecessary.

A simple pronunciation guide would be:

o ar-hi-GHOS mi-LA-i TO-ra

More carefully:

• Ο = o
• αρχηγός = ar-hi-GHOS
• μιλάει = mi-LA-i
• τώρα = TO-ra

Notes:

• The stress is on -γός in αρχηγός
• The stress is on λά in μιλάει
• The stress is on τώ in τώρα

In Modern Greek, the accent mark shows which syllable is stressed.

So:

• αρχηγός → stress on the last syllable
• μιλάει → stress on λά
• τώρα → stress on the first syllable

Stress matters in Greek pronunciation, so the accent marks are important and should be learned as part of the word.

Yes, in this sentence it is quite similar:

• Ο αρχηγός = subject
• μιλάει = verb
• τώρα = time expression

So it follows a familiar subject + verb + time word pattern.

But Greek is generally more flexible than English, because grammatical endings help show what each word is doing.

It is neutral and natural.

Nothing in Ο αρχηγός μιλάει τώρα. is especially formal or especially casual. It would work in many contexts, such as:

• a meeting
• a classroom
• a political speech
• a team setting

So it is a good everyday model sentence.
