La konekto estas sendrata.

La is Esperanto’s definite article, equivalent to English the.

So la konekto means the connection, not just a connection. Esperanto has no separate word for a/an, so an indefinite noun usually appears without any article.

In this sentence, la suggests that the speaker means a specific connection already known from the context.

Because -o is the normal noun ending in Esperanto.

So:

• konekt- = the root
• konekto = connection

This is one of the most basic patterns in Esperanto: if a word ends in -o, it is a noun.

Estas is the present-tense form of esti, meaning to be.

So:

• mi estas = I am
• vi estas = you are
• ĝi estas = it is

A useful feature of Esperanto is that the verb does not change depending on the subject. Estas always means present-tense am/is/are.

Because -a is the adjective ending in Esperanto.

Sendrata is an adjective meaning wireless. It describes konekto.

So the sentence structure is:

• La konekto = the connection
• estas = is
• sendrata = wireless

This is like English The connection is wireless, where wireless is describing the connection.

It is made from smaller Esperanto parts:

• sen = without
• drat- = wire
• -a = adjective ending

So sendrata literally means something like without-wire or wireless.

A very common Esperanto pattern is to build words from smaller meaningful pieces like this.

Because in compounds, Esperanto normally uses the root, not the full standalone word.

So:

• standalone noun: drato = wire
• root used in compounds: drat-

That is why you get sendrata, not sendratoa or something similar.

This is completely normal in Esperanto word-building.

Because there is no direct object here.

La konekto is the subject, and sendrata is a predicate adjective after estas. After esti and similar verbs, you do not use the accusative -n just because a word comes later in the sentence.

So this is correct:

• La konekto estas sendrata.

Not:

• La konekton estas sendrata.
• La konekto estas sendratan.

Yes. Adjectives agree with the nouns they describe in number and case.

In this sentence, konekto is singular and has no accusative -n, so the adjective is also singular and has no -n:

• konekto
• sendrata

If it were plural, you would say:

• La konektoj estas sendrataj.

So agreement is an important rule in Esperanto.

Yes, but then the structure changes.

• La konekto estas sendrata = The connection is wireless.
• La sendrata konekto = The wireless connection.

So yes, sendrata can go before the noun when it directly modifies it, but in your original sentence it comes after estas because it is part of the predicate.

This is the most natural and neutral word order:

• subject: La konekto
• verb: estas
• description: sendrata

Esperanto word order is somewhat flexible, but this sentence is the standard straightforward way to say it.

For a learner, this is the best pattern to remember: noun + estas + adjective

The stress in Esperanto normally falls on the second-to-last syllable of each word.

So the stress is:

• ko-NEK-to
• ES-tas
• sen-DRA-ta

A rough guide for an English speaker would be:

• lah ko-NEK-to ES-tahs sen-DRAH-tah

The vowels are pure and consistent:

• a as in father
• e as in bed
• o as in for but shorter and purer

Not necessarily. Sendrata means wireless in a general sense.

So it can describe anything that works without wires, such as:

• a wireless connection
• a wireless network
• a wireless device

If the meaning is specifically Wi-Fi, context usually makes that clear, or a more specific term may be used.

Yes. Esperanto makes word families very regularly.

From the same root konekt-, you can get:

• konekti = to connect
• konekto = connection
• konekta = connected / relating to connection
• malkonekti = to disconnect

This regularity is one of the biggest advantages of Esperanto for learners.
