La leĝo gravas por la socio.

This is a very common question. Esperanto uses la more often than English does, especially when talking about something in a general, whole-category sense.

So:

• La leĝo = the law, but it can also mean law in general / the institution of law
• La socio = society, often where English does not need the

In Esperanto, la is often used with abstract or general concepts when they are viewed as a known whole.

So La leĝo gravas por la socio is a normal way to say that law, as an institution or principle, matters for society.

Without la, the sentence would sound less natural in this context.

Gravas comes from the root grav-, meaning important / serious / weighty.

Esperanto often lets you turn an idea like to be important into a verb directly:

• grava = important
• gravas = is important / matters

So:

• La leĝo gravas = The law is important / The law matters
• La leĝo estas grava = The law is important

Both are correct. The version with gravas is a little more compact and often feels very natural in Esperanto.

This is a common Esperanto pattern:

• utila = useful → utilas = is useful
• necesa = necessary → necesas = is necessary

In Esperanto, -as is the present-tense verb ending.

So:

• gravas = is important / matters
• gravis = was important / mattered
• gravos = will be important / will matter

Even though English often uses an adjective with is, Esperanto can express the same idea with a verb, and then that verb takes the normal tense ending.

Por usually means for.

In this sentence, it shows who is affected or benefited:

• La leĝo gravas por la socio = The law is important for society

So por la socio tells us that society is the one for whom the law is important.

Because por is a preposition, and after a normal preposition you usually do not add -n.

So:

• por la socio = for society

The accusative -n is mainly used for:

1. the direct object
2. motion toward something in some cases

But here, la socio is just the object of the preposition por, so there is no -n.

Because the sentence does not have a direct object.

Breakdown:

• La leĝo = the subject
• gravas = the verb
• por la socio = a prepositional phrase

The verb gravi does not take a direct object here. It just says that something is important. So there is no need for -n.

Leĝo is pronounced approximately like LED-zho or LEH-joh, depending on how you prefer to approximate it for an English speaker.

The special letter here is ĝ:

• ĝ sounds like the j in judge
• o is a pure o sound, not the English diphthong in go

So leĝo is roughly:

• LEH-zho

with stress on the second-to-last syllable:

• LEH-ĝo

Esperanto always stresses the next-to-last syllable.

They are different parts of speech:

• grava = an adjective, important
• gravas = a verb, is important / matters

So you can say either:

• La leĝo estas grava por la socio.
• La leĝo gravas por la socio.

The first literally means The law is important for society.
The second means almost the same thing, but in a more verb-like way: The law matters for society or The law is important for society.

Yes. That is completely correct.

The two versions are very close:

• La leĝo gravas por la socio.
• La leĝo estas grava por la socio.

The first is a more compact Esperanto style. The second may feel more familiar to an English speaker because it uses to be + adjective.

In Esperanto, socio means society in the broad social sense.

So:

• la socio = society

Be careful not to confuse it with similar-looking words in other languages or with English-based guesses.

A related word is:

• societo = an association, company, or society in the sense of an organized group

So in this sentence, la socio is the right choice if you mean society as a whole.

The structure is:

• La leĝo = subject
• gravas = verb
• por la socio = prepositional phrase

So literally:

• The law matters for society

This is a very normal Esperanto word order: subject + verb + other information.

Yes, Esperanto word order is fairly flexible, because endings make the roles clearer than in English.

For example, you could say:

• Por la socio gravas la leĝo.

That might put more emphasis on for society.

But the most neutral and straightforward order is the original:

• La leĝo gravas por la socio.

Not exactly.

• leĝo = law
• regulo = rule
• regularo = a set of rules / regulations

So leĝo usually refers to law in the legal or general normative sense, not just a rule of a game or a classroom instruction.

It can often mean both, depending on context.

So:

• La leĝo gravas por la socio can be understood as
  • The law is important for society
  • The law matters for society

In many cases, English uses either expression naturally, and Esperanto gravas covers that idea well.

Because Esperanto always stresses the second-to-last syllable.

socio has three syllables:

• so-ci-o

The second-to-last syllable is ci, so the stress is there:

• so-CI-o

This rule applies to all normal Esperanto words, which makes pronunciation very predictable.
