Όσο κι αν είναι μικρή, η δωρεά βοηθά τον φιλανθρωπικό οργανισμό.

It introduces a concessive idea: however / no matter how.

So Όσο κι αν είναι μικρή means however small it is or no matter how small it is.

In this pattern, όσο is not simply as much as. Together with κι αν, it means to whatever degree.

Κι is a very common shortened form of και.

Here, κι αν is especially natural because κι comes before a vowel sound. It means the same as και in this expression, so:

• όσο κι αν
• όσο και αν

are basically the same, but κι is more natural and common in everyday Greek.

Because it describes η δωρεά, and δωρεά is a feminine singular noun.

Greek adjectives must agree with the noun they describe in gender and number:

• μικρός = masculine
• μικρή = feminine
• μικρό = neuter

So with η δωρεά, the correct form is μικρή.

Greek often allows the subject to appear later, especially when a subordinate clause comes first.

In Όσο κι αν είναι μικρή, the subject is understood as it, and that it refers to η δωρεά, which appears in the main clause:

• Όσο κι αν είναι μικρή,
• η δωρεά βοηθά...

This is normal Greek structure and sounds natural.

Because the first part, Όσο κι αν είναι μικρή, is a subordinate clause, and the second part, η δωρεά βοηθά τον φιλανθρωπικό οργανισμό, is the main clause.

The comma separates:

• the concessive clause: Όσο κι αν είναι μικρή
• the main clause: η δωρεά βοηθά τον φιλανθρωπικό οργανισμό

English usually does the same: However small it is, the donation helps the charity.

Not necessarily in the very specific English sense of the donation.

Greek uses the definite article much more often than English. In a sentence like this, η δωρεά can be understood generically, meaning something like:

• a donation
• any donation
• donation, in general

So Greek may use η, even where English would not always use the.

If you said μια δωρεά, that would sound more like a/one donation as an individual instance.

Because it is the direct object of βοηθά.

The verb βοηθώ takes an object in the accusative case, so:

• ο φιλανθρωπικός οργανισμός = nominative, the charitable organization (subject form)
• τον φιλανθρωπικό οργανισμό = accusative, the charitable organization (object form)

The adjective also changes to match the noun:

• φιλανθρωπικός οργανισμός
• φιλανθρωπικό οργανισμό

Βοηθά is the 3rd person singular present tense of βοηθώ.

So it means:

• he/she/it helps
• in this sentence: the donation helps

The subject is η δωρεά, which is singular, so βοηθά must also be singular.

No. Greek word order is fairly flexible.

A very common alternative is:

Όσο μικρή κι αν είναι, η δωρεά βοηθά τον φιλανθρωπικό οργανισμό.

That version places μικρή closer to όσο, which many learners may find easier to recognize as however small.

Both are understandable, but the original sentence is perfectly natural.

It is a predicate adjective.

That means it comes after the verb είναι and describes the subject:

• η δωρεά είναι μικρή = the donation is small

So in the full sentence, the first clause literally has the structure:

• however
• it is
• small

That is why μικρή is not directly next to δωρεά, even though it still describes it.
