Το φωτογραφικό φλας είναι δυνατό.

Το is the neuter singular definite article, meaning the.

It is used here because φλας is treated as a neuter noun in Greek, so the article has to match it:

• το φλας = the flash

If you wanted a flash instead, you would say:

• ένα φωτογραφικό φλας

So το is not just a separate word for the in general; it is specifically the form of the that matches a neuter singular noun.

Because φωτογραφικό is an adjective describing φλας, and adjectives in Greek must agree with the noun they describe in gender, number, and case.

The dictionary form is φωτογραφικός = photographic, but its endings change:

• masculine: φωτογραφικός
• feminine: φωτογραφική
• neuter: φωτογραφικό

Since φλας is neuter singular, the adjective must also be neuter singular:

• το φωτογραφικό φλας

For the same reason: δυνατό is an adjective, and it must agree with the subject το φωτογραφικό φλας, which is neuter singular.

The basic forms are:

• masculine: δυνατός
• feminine: δυνατή
• neuter: δυνατό

So:

• ο άντρας είναι δυνατός
• η γυναίκα είναι δυνατή
• το φλας είναι δυνατό

Even though δυνατό comes after είναι, it still agrees with the subject.

Δυνατός has a broad meaning in Greek. Depending on context, it can mean:

• strong
• powerful
• intense
• loud

With φλας, it does not mean physically strong. It means something like:

• powerful
• bright
• intense

So in this sentence, δυνατό describes the strength or intensity of the flash.

Φλας is a loanword in Greek, ultimately from English/French usage. In modern Greek it is very common and usually treated as a neuter noun:

• το φλας

It can refer to more than one thing depending on context, especially:

• a camera flash
• a car turn signal / blinker

That is why φωτογραφικό is helpful here: it makes clear that this is the photographic flash, not the car signal.

Because in Greek, adjectives often come before the noun in normal, neutral style:

• το φωτογραφικό φλας

This is very natural Greek word order.

Greek does allow some flexibility, but for a learner, the safest pattern is:

• article + adjective + noun

So this sentence is using a very standard structure.

In a normal full sentence, yes.

Είναι is the present tense of to be, so the structure is:

• Το φωτογραφικό φλας = the camera flash
• είναι = is
• δυνατό = powerful / strong / bright

So the whole sentence follows the familiar pattern:

• subject + is + adjective

In very informal notes, headlines, or special styles, Greek sometimes leaves out είναι, but in standard everyday sentence building, you should include it.

Yes, Greek has more flexible word order than English, but this version is the most neutral and straightforward:

• Το φωτογραφικό φλας είναι δυνατό.

That is the best form for learners to use.

Other word orders are possible for emphasis, but they can sound marked or stylistically different. In ordinary speech and writing, the sentence as given is the most natural basic pattern.

A simple pronunciation guide is:

• Το = to
• φωτογραφικό = fo-to-gra-fi-KO
• φλας = flas
• είναι = EE-ne
• δυνατό = thi-na-TO

A few helpful points:

• φ sounds like English f
• δ in modern Greek sounds like th in this
• the stress is on -κό in φωτογραφικό
• the stress is on -τό in δυνατό

So the whole sentence sounds roughly like:

to fo-to-gra-fi-KO flas EE-ne thi-na-TO

Yes, literally it is very close to that.

Word by word:

• Το = the
• φωτογραφικό = photographic
• φλας = flash
• είναι = is
• δυνατό = strong / powerful

But in natural English, you would usually say something like:

• The camera flash is powerful
• The flash is strong
• The flash is bright

So the Greek wording is straightforward, but the most natural English translation depends on context.
