Η παροχή έχει μετρητή και η ένδειξη είναι εδώ.

Because both nouns are feminine singular and are the subjects of their clauses.

• η παροχή = the supply / connection
• η ένδειξη = the reading / indication

In Greek, the definite article agrees with the noun in gender, number, and case. Here both are nominative singular feminine, so the article is η.

Literally, παροχή can mean supply, provision, or service. In practical contexts like electricity, water, or gas, it often means the utility connection / supply point / service line.

So in this sentence, it probably does not mean a general abstract provision. It is more likely talking about a specific utility connection.

Έχει is the 3rd person singular present of έχω (to have).

So:

• έχω = I have
• έχεις = you have
• έχει = he/she/it has

Here the subject is η παροχή, which is singular, so Greek uses έχει.

Greek normally does not have a separate indefinite article like English a/an in the same way.

So:

• μετρητή can mean a meter
• if you want extra emphasis, Greek can use έναν: έναν μετρητή

But in ordinary Greek, just saying έχει μετρητή is perfectly natural and usually the most normal way to say has a meter.

Because μετρητή is the accusative singular form, and it is the direct object of έχει.

Dictionary form:

• ο μετρητής = the meter

In the sentence:

• έχει μετρητή = has a meter

This is a very common pattern with masculine nouns ending in -ης:

• nominative: ο μετρητής
• accusative: τον μετρητή

When the article is omitted, you still keep the accusative noun form: μετρητή.

Ένδειξη literally means indication, reading, or displayed value, depending on context.

In a meter-related sentence, it most likely means the meter reading or the indicated value. In other contexts, it could mean a more general indication or sign.

So this is one of those words whose best English translation depends on the situation.

Because και is joining two separate clauses, and each clause has its own subject:

• Η παροχή έχει μετρητή
• και η ένδειξη είναι εδώ

Greek normally keeps the article with each definite noun phrase. English sometimes feels more economical, but in Greek this is completely standard.

Yes. Greek often leaves out subject pronouns because the verb ending already shows the person.

For example, Greek does not need something like it has with an extra pronoun. The subject is already clear from the noun:

• Η παροχή έχει...

You would only add a pronoun for emphasis or contrast.

That is a very natural Greek word order.

• η ένδειξη είναι εδώ = the reading is here

Greek word order is more flexible than English because endings carry a lot of grammatical information. Putting εδώ at the end is normal and often sounds neutral. It places the location as the final piece of information.

Other orders are possible in Greek, but this one is straightforward and natural.

Not exactly fixed, but it is a very common pattern.

Greek often uses:

• είμαι / είναι
  • adverb of place

Examples:

• είναι εδώ = is here
• είναι εκεί = is there
• είναι μέσα = is inside

So once you know είναι, you can use it with many location words in the same way.

A rough English-style pronunciation guide is:

ee pa-ro-KHEE E-khee me-tree-TEE kee ee EN-thee-ksee EE-ne e-THO

A few important points:

• η sounds like ee
• χ in έχει is not an English h; it is a throat/friction sound
• δ in ένδειξη sounds like th in this
• ξ sounds like ks
• the stressed syllables are:
  • παροχή
  • έχει
  • μετρητή
  • ένδειξη
  • εδώ

Yes, that is possible.

• Η παροχή έχει μετρητή
• Η παροχή έχει έναν μετρητή

Both can mean the connection has a meter.

The version without έναν is often more neutral and natural in everyday Greek. Adding έναν can make the noun feel a little more explicitly one / a certain meter, or just slightly more specific.
