Η απώλεια δηλώνεται σήμερα.

Η is the definite article meaning the.

So:

• η απώλεια = the loss

Greek articles change for gender, number, and case. Here:

• η = feminine singular nominative
• απώλεια is a feminine noun

Because απώλεια is the subject of the sentence, it appears in the nominative, and the article matches it.

Απώλεια is a noun, and it is feminine.

In this sentence it is:

• singular
• nominative
• the subject of the verb

So the basic structure is:

• Η απώλεια = the subject
• δηλώνεται = the verb
• σήμερα = today

A learner may notice that many Greek nouns ending in -α are feminine, and απώλεια follows that pattern, even though its ending is slightly longer: -εια.

Because δηλώνεται is a passive/middle form, while δηλώνει is the active form.

Compare:

• δηλώνει = he/she/it declares or states
• δηλώνεται = is declared or is being declared

So:

• Η απώλεια δηλώνεται σήμερα. = The loss is declared/reported today.

This is one of the most important things to notice in the sentence: the action is not something the loss does; rather, the loss is the thing being declared.

Yes, in this sentence you should understand δηλώνεται as a passive form: is declared / is reported.

Greek uses forms traditionally called middle-passive in the present system. That means the same set of endings can express meanings that are:

• truly passive
• middle/reflexive in some contexts
• sometimes just standard dictionary behavior for certain verbs

Here, the most natural interpretation is passive:

• δηλώνω = I declare / report
• δηλώνομαι or forms like δηλώνεται = I am declared / it is declared

So for learning purposes, it is perfectly fine to treat δηλώνεται here as is declared.

Δηλώνεται is:

• 3rd person
• singular
• present tense
• middle-passive voice

Why 3rd person singular? Because the subject is η απώλεια = the loss, which is singular.

So the agreement is:

• η απώλεια → singular subject
• δηλώνεται → 3rd person singular verb

Greek present tense often covers what English expresses with:

• is reported
• is being reported
• sometimes even a more general present-time statement

So δηλώνεται can mean:

• is declared
• is being declared
• gets declared, depending on context

The adverb σήμερα = today anchors the action in the present time frame.

Greek does not always make the same sharp distinction English makes between simple present and progressive forms.

Yes, σήμερα could be placed elsewhere. Greek word order is often more flexible than English word order.

This sentence:

• Η απώλεια δηλώνεται σήμερα.

is a neutral, natural way to say it.

But Greek could also say:

• Σήμερα δηλώνεται η απώλεια.
• Η απώλεια σήμερα δηλώνεται.

These alternatives may shift the emphasis slightly:

• putting σήμερα first can emphasize today
• keeping it at the end often sounds neutral and straightforward

So the end position here is normal, but not the only possibility.

Yes, Greek often allows subjects to be omitted when they are understood from context. Greek is a pro-drop language.

So:

• Δηλώνεται σήμερα.

could be a complete sentence in context, meaning something like:

• It is declared/reported today.

However, in your sentence the subject is included explicitly:

• Η απώλεια δηλώνεται σήμερα.

This is useful when the speaker wants to name the thing clearly or when it is new information.

A rough pronunciation guide is:

• i a-PO-li-a dhi-LO-ne-te SI-me-ra

A few helpful points:

• η is pronounced like ee in see
• ώ shows the stress in απώλεια: a-PO-li-a
• δη sounds like dhi, with δ pronounced like th in this
• λών is stressed in δηλώνεται
• σήμερα is stressed on the first syllable: SI-me-ra

A more careful approximation:

• ee a-POH-lya thee-LOH-ne-te SEE-me-ra

Depending on speaking speed, απώλεια may sound a bit compressed, almost like a-PO-lya.

The dictionary form you are most likely to look up is δηλώνω, meaning I declare / I report / I state.

From that active verb you get the present middle-passive forms, such as:

• δηλώνομαι = I am declared / I declare myself, depending on context
• δηλώνεται = he/she/it is declared

So if you are searching for this verb, start with δηλώνω.

It sounds fairly neutral to formal, especially because of the word δηλώνεται, which is common in administrative, legal, official, or procedural contexts.

For example, this kind of wording could appear in:

• forms
• notices
• regulations
• official instructions

If the context is something like reporting a loss of property, an ID card, or a document, the phrasing fits very naturally.

So it is not unnatural Greek, but it does have a somewhat official feel rather than a casual conversational one.

Greek, like English, often uses the passive without mentioning the agent when the agent is:

• unknown
• obvious
• unimportant
• intentionally left unspecified

So:

• Η απώλεια δηλώνεται σήμερα.

focuses on the loss and the fact that the declaration/report happens today, not on who performs the action.

If needed, Greek can add the agent, but very often it does not.

Σήμερα is an adverb, so it does not have case.

This is important because English speakers sometimes look for case endings everywhere in Greek. But adverbs like σήμερα behave differently from nouns and articles.

So:

• η απώλεια = noun phrase with article, gender, number, case
• δηλώνεται = verb
• σήμερα = adverb meaning today

Yes. Απώλεια is a broad noun and can refer to different types of loss depending on context, for example:

• loss of an object
• financial loss
• loss of data
• emotional or personal loss

In a sentence like this one, especially with δηλώνεται, many learners will understand it as something like an officially reported loss, such as the loss of a document, item, or property.

So the exact nuance comes from the wider situation, not just from the noun itself.
