Η ρωγμή είναι στη λαβή.

Η is the feminine singular definite article, meaning the.

It is used here because ρωγμή is a feminine singular noun, and in this sentence it is the subject, so it appears in the nominative case:

• η ρωγμή = the crack

So Η ρωγμή is the subject of the sentence.

Greek often uses the definite article where English uses the.

So if the sentence means the crack, Greek normally says η ρωγμή. Leaving out the article would make it sound less natural in a normal statement like this, unless the context specifically called for it.

Είναι is the present-tense form of είμαι, which means to be.

In this sentence, it means is:

• Η ρωγμή είναι... = The crack is...

A useful thing to know is that είναι can mean either is or are, depending on the subject:

• Η ρωγμή είναι... = The crack is...
• Οι ρωγμές είναι... = The cracks are...

Στη is the contracted form of:

• σε = in / at / on / to
• τη = the (feminine accusative singular)

So:

• σε τη λαβή → στη λαβή

This contraction is completely normal and very common in modern Greek.

So στη λαβή means in the handle or on the handle, depending on context.

Yes. The preposition σε normally takes the accusative case in modern Greek.

That is why λαβή here is understood as accusative. In this particular noun, though, the noun form itself looks the same in nominative and accusative singular:

• nominative: η λαβή
• accusative: τη λαβή

So the article changes, but the noun λαβή stays the same.

Both forms come from σε την.

In standard modern Greek, the final -ν is usually kept before:

• vowels
• and certain consonants such as κ, π, τ, ξ, ψ and some consonant clusters

Since λαβή starts with λ, the usual form is:

• στη λαβή

You may still sometimes hear or see στην in some varieties of Greek or in careful speech, but στη λαβή is the normal standard form here.

Ρωγμή is simply a noun whose grammatical gender is feminine. In Greek, every noun has a grammatical gender: masculine, feminine, or neuter.

The ending -ή is very often feminine, so that helps learners guess the gender:

• η ρωγμή
• η λαβή

But it is still best to learn nouns together with their article, because gender is something you need to memorize:

• η ρωγμή
• η λαβή

A simple pronunciation guide is:

• Η → ee
• ρωγμή → roughly rogh-MEE
• είναι → roughly EE-neh
• στη → stee
• λαβή → roughly la-VEE

A few useful pronunciation notes:

• ω and ο are both pronounced o in modern Greek.
• β is pronounced v, not English b.
• ή / η / ι / υ / ει / οι all sound like ee in modern Greek.
• The written accent mark shows which syllable is stressed:
  • ρωγμή → stress on the last syllable
  • λαβή → stress on the last syllable
  • είναι → stress on the first syllable

Yes. Greek word order is more flexible than English word order.

The neutral, straightforward order here is:

• Η ρωγμή είναι στη λαβή.

But Greek could also say something like:

• Στη λαβή είναι η ρωγμή.

That would sound more marked, with extra focus on the handle as the location.

So the original sentence is the most neutral and natural way to say it.

Usually ρωγμή means a crack, split, or fissure, especially a line or opening in a surface or object.

It is a fairly specific word, not just any kind of damage. Depending on context, Greek might use other words for things like:

• a break
• a fracture
• a smash
• a chip

But ρωγμή is a good match for crack in a sentence like this.

The sentence follows a very clear pattern:

• Η ρωγμή = subject
• είναι = verb
• στη λαβή = prepositional phrase showing location

So the structure is:

subject + to be + location

This is a very common and useful pattern in Greek, for example:

• Το βιβλίο είναι στο τραπέζι. = The book is on the table.
• Το κλειδί είναι στην τσέπη. = The key is in the pocket.
• Η ρωγμή είναι στη λαβή. = The crack is in the handle.
