Η κοινωνική δομή βοηθά την ευάλωτη ομάδα.

Because βοηθά is a transitive verb here, so it takes a direct object.

• η κοινωνική δομή = nominative singular feminine, so it is the subject: the thing doing the action.
• την ευάλωτη ομάδα = accusative singular feminine, so it is the direct object: the thing receiving the action.

A learner can spot this mostly from the article:

• η = nominative feminine singular
• την = accusative feminine singular

So Greek is showing the grammar through the article and endings, not just through word order.

Because adjectives in Greek must agree with the noun they describe.

Here:

• δομή is a feminine singular noun
• so κοινωνική must also be feminine singular nominative

This is called agreement. Greek adjectives agree with nouns in:

• gender
• number
• case

So:

• η κοινωνική δομή = feminine singular nominative
• την ευάλωτη ομάδα = feminine singular accusative

That is why the adjective changes form depending on the noun.

Because this phrase is the direct object, not the subject.

After βοηθά in this sentence, the thing being helped is the object, so Greek uses the accusative:

• nominative: η ευάλωτη ομάδα
• accusative: την ευάλωτη ομάδα

Notice that both the article and the adjective reflect this:

• η ευάλωτη ομάδα = subject form
• την ευάλωτη ομάδα = object form

For feminine nouns like ομάδα, the noun itself may look the same in nominative and accusative singular, but the article shows the difference clearly.

Greek uses the definite article much more often than English.

So η κοινωνική δομή and την ευάλωτη ομάδα sound natural in many contexts where English might or might not use the.

You often cannot omit the article in Greek if you are talking about a specific or understood thing. Without the article, the sentence could sound less natural or more abstract, depending on context.

So although English article usage may differ, in Greek:

• η κοινωνική δομή
• την ευάλωτη ομάδα

is a very normal, natural structure.

βοηθά is the common 3rd person singular present form of βοηθώ in Modern Greek.

So:

• εγώ βοηθώ = I help
• αυτός / αυτή / αυτό βοηθά = he / she / it helps

You may also encounter forms related to a more learned or formal pattern, but βοηθά is the normal everyday form for he/she/it helps.

In this sentence, the subject is singular:

• η κοινωνική δομή = social structure

So the verb must also be singular:

• βοηθά

The accent marks where the stress goes in pronunciation.

So βοηθά is stressed on the last syllable:

• bo-i-thA

This matters because Greek spelling regularly shows stress. If you move the accent, you may get a different form or something incorrect.

The same is true for the other words:

• κοινωνική
• δομή
• ευάλωτη
• ομάδα

Learning to notice written stress is very important in Greek.

A rough pronunciation guide is:

i kinee-no-nee-KEE tho-MEE vo-ee-THA teen e-VA-lo-tee o-MA-tha

A few useful notes:

• η sounds like ee
• κοι in κοινωνική sounds roughly like kee here
• δ in Modern Greek sounds like the th in this, not like English d
• θ sounds like the th in think
• ευ can sound like ev or ef depending on the following sound; here in ευάλωτη it sounds like ev
• η / ι / υ / ει / οι often sound like ee in Modern Greek

The stress falls on:

• κοινωνική
• δομή
• βοηθά
• ευάλωτη
• ομάδα

Yes. Greek word order is more flexible than English because case endings help show who is doing what.

The neutral order here is:

• Η κοινωνική δομή βοηθά την ευάλωτη ομάδα.

But Greek can move things around for emphasis, for example:

• Την ευάλωτη ομάδα βοηθά η κοινωνική δομή.

That still means the same basic thing, because:

• η κοινωνική δομή is still nominative
• την ευάλωτη ομάδα is still accusative

So in Greek, word order often affects emphasis more than core grammatical meaning.

You would usually look up:

• δομή for δομή
• κοινωνικός, -ή, -ό for κοινωνική
• βοηθώ for βοηθά
• ευάλωτος, -η, -ο for ευάλωτη
• ομάδα for ομάδα

Greek adjectives are often listed in a masculine-feminine-neuter pattern, such as:

• κοινωνικός, κοινωνική, κοινωνικό
• ευάλωτος, ευάλωτη, ευάλωτο

Verbs are normally looked up in the 1st person singular present:

• βοηθώ

Yes. In Modern Greek, βοηθώ normally takes a direct object in the accusative:

• βοηθώ τον φίλο μου
• βοηθά την ομάδα
• βοηθούμε τους μαθητές

So in your sentence:

• την ευάλωτη ομάδα is accusative because it is the thing being helped

This is worth noticing because some older stages of Greek, or some formal expressions, may behave differently, but in standard Modern Greek the accusative is what learners should use here.

Usually yes, or very close.

ευάλωτη means vulnerable, easily harmed, or at risk, depending on context. So ευάλωτη ομάδα is a very common type of phrase meaning a vulnerable group.

It is a good example of an adjective that changes form to match the noun:

• ευάλωτος = masculine
• ευάλωτη = feminine
• ευάλωτο = neuter

Since ομάδα is feminine, the sentence uses ευάλωτη.

Because it is a one-syllable word, and in Modern Greek monosyllabic words usually do not take a written accent.

So:

• η
• την

do not need accent marks

By contrast, longer words do show stress:

• κοινωνική
• δομή
• βοηθά
• ευάλωτη
• ομάδα

This is completely normal Greek spelling.

You learn it from the article and from the noun itself.

Here:

• η δομή = feminine
• η ομάδα = feminine

Many Greek nouns ending in -ή or -α are feminine, though you should not rely on endings alone every time. The safest habit is to learn nouns together with their article:

• η δομή
• η ομάδα

That way you automatically learn the gender and a key case form at the same time.
