Η καλοσύνη βοηθάει όλους.

Η is the feminine singular definite article, equivalent to the.

In Greek, abstract nouns are often used with the definite article much more than in English. So Η καλοσύνη is literally the kindness, but in natural English it is usually translated simply as kindness.

So this is very normal Greek, not something unusually specific.

καλοσύνη is a noun meaning kindness or goodness.

It is:

• feminine
• singular
• here in the nominative case, because it is the subject of the sentence

So Η καλοσύνη = kindness as the thing doing the action.

βοηθάει is the third person singular present tense form of βοηθάω / βοηθώ, meaning to help.

It means:

• he helps
• she helps
• it helps

In this sentence, the subject is Η καλοσύνη (kindness), which is singular, so the verb must also be singular:

• Η καλοσύνη βοηθάει = Kindness helps

Yes. Both βοηθάει and βοηθά are used in Modern Greek.

They both mean the same thing here:

• Η καλοσύνη βοηθάει όλους
• Η καλοσύνη βοηθά όλους

The longer form -άει is very common in everyday Greek, and the shorter form -ά is also correct.

Because όλους is in the accusative case, which is used for the direct object.

In this sentence, kindness is doing the helping, and everyone / all people is receiving the action, so Greek uses the accusative:

• subject: Η καλοσύνη
• object: όλους

Compare:

• όλοι = all / everyone as a subject
• όλους = all / everyone as an object

So after helps, Greek needs όλους.

In Greek, the masculine plural is often used for a mixed group or for people in general when gender is not specified.

So όλους here means:

• everyone
• all people
• all of them, depending on context

It does not mean only males in this kind of general statement. It is a normal generic use.

It comes from όλος (all, whole), which is often an adjective, but here it is being used on its own, so it functions like a pronoun.

So όλους here means something like:

• everyone
• all people

You could think of it as a shortened form of something like όλους τους ανθρώπους = all people / all humans.

A simple pronunciation guide is:

i ka-lo-SI-ni vo-i-THA-i O-lous

A few useful sound notes:

• Η sounds like ee in see
• β sounds like v, not English b
• θ sounds like th in think
• ει usually sounds like ee
• ου sounds like oo in food

So βοηθάει begins with a v sound: vo-...

Greek uses accent marks to show which syllable is stressed.

So:

• καλοσύνη
• βοηθάει
• όλους

This is important for correct pronunciation. The accent is not optional in normal writing.

Yes. Greek word order is more flexible than English because the endings show the grammatical roles.

The neutral, straightforward order here is:

• Η καλοσύνη βοηθάει όλους.

But other orders are possible for emphasis, for example:

• Όλους βοηθάει η καλοσύνη.

That would still mean basically Kindness helps everyone, but with more emphasis on everyone.

It is grammatically natural Greek. It sounds a bit like a general statement or moral idea, which is common in learning materials, sayings, and simple examples.

In everyday speech, a speaker might also say similar things like:

• Η καλοσύνη βοηθά τους ανθρώπους.
• Η καλοσύνη βοηθάει πάντα.

So the sentence is correct and natural, even if it has a slightly proverb-like feel.

No. In Modern Greek, capital and lowercase forms are pronounced the same.

So:

• Η at the beginning of the sentence
• η in the middle of a sentence

both sound like ee.

The only difference is that Η is capitalized because it starts the sentence.
