La tajloro kudris la zipon.

In Esperanto, most basic nouns end in -o. So tajloro is a noun meaning tailor.

A few useful endings here:

• -o = noun
• -a = adjective
• -e = adverb
• -i = infinitive verb

So:

• tajloro = a tailor
• kudri = to sew

La means the.

It appears before both nouns because both are definite:

• la tajloro = the tailor
• la zipon = the zipper

Unlike English, Esperanto uses the same word la for all genders and numbers. It does not change.

Kudris is the past tense of kudri (to sew).

Esperanto verb endings are very regular:

• -as = present
• -is = past
• -os = future
• -us = conditional
• -u = command / jussive
• -i = infinitive

So:

• kudras = sews / is sewing
• kudris = sewed
• kudros = will sew

In this sentence, kudris tells you the action happened in the past.

The -n ending marks the direct object in Esperanto.

Here:

• la tajloro = the subject, the person doing the action
• la zipon = the direct object, the thing being sewn

So zipo means zipper, and zipon means zipper in the direct-object form.

This is called the accusative ending.

The endings tell you.

• la tajloro has no -n, so it is the subject
• la zipon has -n, so it is the direct object

That means the tailor did the sewing, and the zipper is what got sewn.

This is one reason Esperanto word order can be more flexible than English.

Yes. Because zipon has the accusative -n, Esperanto can change the word order more freely without changing the basic meaning.

For example, these still mean the same thing:

• La tajloro kudris la zipon.
• La zipon kudris la tajloro.

However, the first version is the most neutral and natural for beginners because it follows the common subject–verb–object order.

Yes, zipo is a normal Esperanto word for zipper or zip fastener.

Esperanto often borrows international words and adapts them to Esperanto spelling and endings. So zipo fits Esperanto structure neatly:

• root: zip-
• noun ending: -o

Then the accusative makes it zipon.

A helpful approximation is tie-LOR-o.

A few pronunciation points:

• j in Esperanto sounds like English y
• stress is usually on the second-to-last syllable

So:

• tajloro → taj-LO-ro

The taj part sounds roughly like tie.

A rough English-friendly pronunciation is KOO-dris.

Details:

• u sounds like oo in food
• stress goes on the second-to-last syllable

Since kudris has two syllables, the stress is on the first one:

• KU-dris

A rough pronunciation is ZEE-pon.

Notes:

• z is pronounced like English z
• i sounds like ee
• stress is on the second-to-last syllable

So:

• ZI-pon

Because Esperanto verbs do not change according to person or number.

The same verb form is used with all subjects:

• mi kudras = I sew
• vi kudras = you sew
• li kudras = he sews
• ŝi kudras = she sews
• ili kudras = they sew

So kudris would stay kudris no matter who did the action.

Usually tajloro means tailor, especially someone who makes, alters, or repairs clothes.

In context, it strongly suggests a person working with clothing, which fits well with sewing in a zipper.

Depending on context, English might say tailor, seamster, or simply person sewing clothes, but tajloro is the normal straightforward word here.

No. In this sentence, la zipon is the direct object, so it means the zipper is the thing being sewn.

If you wanted to say with the zipper or onto something, Esperanto would normally use a preposition, for example:

• per = with, by means of
• sur = on
• al = to

So the plain accusative here points to the zipper as the object of kudris.
