La hundo estas obeema.

La is the definite article, so it means the.

• la hundo = the dog
• Esperanto uses just one form, la, for all nouns.
• It does not change for gender, number, or case.

So La hundo means the dog, not a dog.

In Esperanto, nouns end in -o.

So:

• hund- = the idea/root related to dog
• hundo = dog

This -o ending is one of the most basic grammar patterns in Esperanto, and it makes parts of speech very easy to recognize.

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

So:

• mi estas = I am
• vi estas = you are
• li/ŝi/ĝi estas = he/she/it is

In this sentence, estas links the subject la hundo with the description obeema.

Because obeema is an adjective, and adjectives in Esperanto end in -a.

Here it describes the dog:

• hundo = dog
• obeema = obedient

So the structure is:

• La hundo = the dog
• estas = is
• obeema = obedient

Obeema is made from smaller meaningful parts:

• obe- = related to obeying
• -em- = inclined to, having a tendency toward
• -a = adjective ending

So obeema literally means something like inclined to obey or obedient.

This is a very common Esperanto pattern: roots and affixes combine in a regular way.

There is no -n because nothing here is a direct object.

In La hundo estas obeema:

• la hundo is the subject
• obeema is a description linked by estas

After esti (to be), you usually have a predicate noun or predicate adjective, not a direct object. So no accusative -n is needed here.

Actually, it already matches the noun: both are singular and nominative.

In Esperanto, adjectives agree with the nouns they describe in number and case.

Here:

• hundo = singular, no -n
• obeema = singular, no -n

If the noun changed, the adjective would change too:

• La hundoj estas obeemaj. = The dogs are obedient.
• Mi vidas la obeeman hundon. = I see the obedient dog.

So in your sentence, obeema is the correct matching form.

Yes. Subject + verb + complement is the most neutral and common order here:

• La hundo = subject
• estas = verb
• obeema = complement/description

Esperanto word order is fairly flexible, but this version is the most straightforward for a beginner.

Yes, but it would change the meaning slightly.

• La hundo estas obeema. = The dog is obedient.
• Hundo estas obeema. would sound more like A dog is obedient or Dog is obedient, depending on context.

In many situations, leaving out la makes the noun less specific.

It is pronounced roughly o-be-E-ma, with the stress on the second-to-last syllable: E.

A useful rule in Esperanto is that stress almost always falls on the next-to-last syllable.

So:

• o-be-E-ma

That stress rule is very regular and helps a lot with pronunciation.

Usually obeema suggests a characteristic or tendency: the dog is obedient by nature or behavior.

Because of the suffix -em-, it often feels like prone to obey, disposed to obey, or habitually obedient, not just obedient in one single moment.

So it often sounds more like a trait than a temporary condition.
