La komercisto marĉandas pri la tekruĉo.

Komercisto can be divided like this:

• komerc- = trade, commerce
• -ist- = a person professionally involved in something, or identified by that activity
• -o = noun ending

So komercisto is a merchant / trader as a role or profession.

A learner might wonder about komercanto. That would mean someone who is trading, with more of an “active participant” sense from -ant-. In many contexts they can be similar, but komercisto is the more natural word for merchant as a profession.

La is Esperanto’s definite article, meaning the.

It appears before both komercisto and tekruĉo because both are being treated as specific things: the merchant and the teapot.

A few useful things about la:

• It never changes form.
• It does not agree with singular/plural or case.
• Esperanto has no separate word for “a/an.”

So:

• la komercisto = the merchant
• komercisto = a merchant / merchant depending on context

In Esperanto, -as marks the present tense.

The dictionary form of the verb is marĉandi. From that:

• marĉandi = to haggle / to bargain
• marĉandas = haggles / is haggling

Esperanto verbs do not change according to the subject, so:

• mi marĉandas
• vi marĉandas
• li marĉandas
• ili marĉandas

all use the same -as ending for the present tense.

Because marĉandi commonly goes with pri when you say what the bargaining is about.

So:

• marĉandi pri io = to haggle over something
• marĉandi kun iu pri io = to haggle with someone over something

In this sentence:

• pri la tekruĉo = over the teapot / about the teapot

This is a good example of how Esperanto often uses a preposition where English might use different phrasing.

Because la tekruĉo is the object of the preposition pri, not a direct object.

In Esperanto, the -n ending is mainly used for:

1. the direct object
2. sometimes direction/motion toward something

But after a preposition like pri, you normally do not add -n.

So:

• pri la tekruĉo = correct
• pri la tekruĉon = not correct here

A useful way to think about it: the verb is not directly acting on the teapot; the merchant is bargaining about/over it.

Tekruĉo is a compound word:

• te- = tea
• kruĉ- = jug, pitcher, pot
• -o = noun ending

So it literally means something like tea-pot / tea-jug, i.e. teapot.

Esperanto very often builds words this way. The final main element usually tells you what kind of thing it is. Here, it is basically a kind of kruĉo connected with te.

Ĉ is pronounced like ch in church.

So roughly:

• marĉandas ≈ mar-CHAN-das
• tekruĉo ≈ te-KROO-cho or more exactly te-KRU-cho

A few pronunciation notes:

• Esperanto stress is usually on the second-to-last syllable.
• So:
  • mar-ĉAN-das
  • te-KRU-ĉo

Also, Esperanto spelling is very regular: one letter usually corresponds to one sound.

Yes. Esperanto word order is more flexible than English because endings and prepositions do a lot of the grammatical work.

The neutral order here is:

• La komercisto marĉandas pri la tekruĉo.

But for emphasis, you could also say:

• Pri la tekruĉo marĉandas la komercisto.

That might emphasize what the bargaining is about.

Still, for learners, the original subject–verb–rest order is the safest and most natural default.

Here it behaves intransitively: the verb is completed with a prepositional phrase, not a direct object.

So the pattern is not:

• marĉandi ion

but rather:

• marĉandi pri io
• marĉandi kun iu pri io

That is why the sentence is structured with pri la tekruĉo instead of using a direct object ending.
