Και οι δύο είναι εδώ τώρα.

That is a very common question. On its own, και usually does mean and. But in the fixed expression και οι δύο, it means both.

So:

• και = and
• οι δύο = the two
• και οι δύο = both / both of them

This is an idiomatic Greek pattern. You should learn και οι δύο as one unit meaning both.

In Greek, οι δύο literally means the two. When Greek says και οι δύο, it gives the sense of both (of them).

Compare:

• δύο άνθρωποι = two people
• οι δύο άνθρωποι = the two people
• και οι δύο άνθρωποι = both people

So the article is not random here. It helps create the meaning both.

Οι is the nominative plural definite article for masculine and feminine nouns.

Examples:

• οι άντρες = the men
• οι γυναίκες = the women

In και οι δύο, it refers to both people/things when the noun is masculine or feminine plural, or when the noun is simply understood from context.

If the things are neuter, Greek usually uses:

• και τα δύο = both of them / both things

So:

• και οι δύο = both of them (masculine/feminine)
• και τα δύο = both of them (neuter)

Είναι is the present tense of to be, used for both:

• he/she/it is
• they are

So in this sentence, είναι means are.

This is normal in Modern Greek: the same form works for both third person singular and third person plural.

Examples:

• Η Μαρία είναι εδώ. = Maria is here.
• Οι φίλοι είναι εδώ. = The friends are here.

Greek often leaves subject pronouns out when they are understood from context. This is very normal.

In this sentence, the subject is already expressed by και οι δύο = both of them, so there is no need to add they.

English:

• Both are here now.

Greek:

• Και οι δύο είναι εδώ τώρα.

You could add a pronoun in some contexts for emphasis, but it is usually unnecessary.

Yes, it is very natural. Greek word order is more flexible than English, but this version is straightforward and neutral.

The sentence is:

• Και οι δύο = both
• είναι = are
• εδώ = here
• τώρα = now

Greek can move elements around for emphasis, for example:

• Και οι δύο είναι τώρα εδώ.
• Εδώ είναι και οι δύο τώρα.
• Τώρα και οι δύο είναι εδώ.

These are possible, but they may sound slightly different in emphasis. The original sentence is a good standard version.

Yes, but the meaning shifts slightly.

• Και οι δύο είναι εδώ τώρα = both are here now
• Οι δύο είναι εδώ τώρα = the two are here now

In many contexts, English might translate both of them similarly, but Greek usually uses και οι δύο when it specifically means both.

So if you want the clear idea of both, keep και.

A simple pronunciation guide is:

Kai i dýo íne edó tóra

A more accurate modern pronunciation is roughly:

ke i DHEE-o EE-ne e-THO TO-ra

A few helpful notes:

• και sounds like ke
• οι is pronounced i
• δύο has the stress on the first syllable: DÝ-o
• είναι sounds like Í-ne
• εδώ has stress on the second syllable: e-DÓ
• τώρα has stress on the first syllable: TÓ-ra

Pronunciation varies a little by speaker and region, but this will serve you well.

The accent marks show which syllable is stressed.

So:

• δύο → stress on δύ-
• είναι → stress on εί-
• εδώ → stress on -δώ
• τώρα → stress on τώ-

These accents are important in written Greek and help you pronounce words correctly.

Notice that και and οι do not have accents here because they are unstressed function words in this sentence.

Modern Greek has several spellings that are pronounced i. This is completely normal and something learners must get used to.

For example, all of these can sound like i in Modern Greek:

• ι
• η
• υ
• ει
• οι

So in this sentence:

• οι is pronounced i

Greek spelling preserves older distinctions, even though modern pronunciation has merged them.

Yes. Very directly:

• εδώ = here
• τώρα = now

Together they mean here now.

In English, here now can sometimes sound dramatic depending on context, but in Greek this combination can be completely ordinary.

Yes. Greek allows τώρα to move around more easily than English allows now.

For example:

• Και οι δύο είναι εδώ τώρα.
• Και οι δύο τώρα είναι εδώ.
• Τώρα και οι δύο είναι εδώ.

All are possible, but the emphasis changes slightly. Putting τώρα earlier often gives it more focus.

The original sentence is neutral and natural.

Not always. If the things are neuter, Greek usually changes οι to τα.

So:

• Και οι δύο είναι εδώ τώρα. = both are here now (masculine/feminine)
• Και τα δύο είναι εδώ τώρα. = both are here now (neuter things)

For example:

• Και τα δύο βιβλία είναι εδώ τώρα. = Both books are here now.

So the article must match the gender of the noun being referred to.

It is neutral and works in both formal and informal Greek. Nothing in it is especially slangy, literary, or overly formal.

You could use it in everyday speech, in writing, or in simple conversation without sounding strange.
