Ni transplantas kaj kultivas la planton; mi tondas unu branĉon.

In Esperanto, -as marks the present tense. So all three verbs mean that the action is happening now or is stated as a general present action.

• transplantas = transplant / are transplanting
• kultivas = cultivate / are cultivating
• tondas = trim / cut / are trimming

This ending does not change with the subject:

• mi transplantas = I transplant
• ni transplantas = we transplant
• li transplantas = he transplants

So Esperanto verbs are much simpler than English verbs in this way.

• ni = we
• mi = I

So the sentence has two clauses:

• Ni transplantas kaj kultivas la planton = We transplant and cultivate the plant
• mi tondas unu branĉon = I trim one branch

The subject changes because the speaker first talks about what we are doing, then about what I am doing specifically. That is completely normal in Esperanto.

The -n ending marks the direct object in Esperanto.

The direct object is the thing that receives the action of the verb.

• Ni transplantas kaj kultivas la planton

  • The thing being transplanted and cultivated is la planto
  • So it becomes la planton

• mi tondas unu branĉon

  • The thing being trimmed is unu branĉo
  • So it becomes unu branĉon

This is one of the most important features of Esperanto grammar.

Because the -n does not depend on the article or determiner. It depends on the word’s role in the sentence.

Both nouns are direct objects:

• la planton = the plant, as object
• unu branĉon = one branch, as object

The article or determiner can vary:

• la planto = the plant
• unu planto = one plant
• tiu planto = that plant

But if the noun is a direct object, it still gets -n:

• la planton
• unu planton
• tiun planton

Yes. La planton is the object of both verbs.

So:

• Ni transplantas kaj kultivas la planton

means:

• We transplant the plant and cultivate the plant.

Esperanto often avoids repeating a word when the meaning is already clear. This is very natural.

Kaj means and.

Here it links the two verbs transplantas and kultivas:

• Ni transplantas kaj kultivas la planton
• We transplant and cultivate the plant

So the same subject (ni) performs both actions, and the same object (la planton) is affected by both actions.

Because la means the, while unu means one.

• la planton refers to a specific plant already identifiable in context
• unu branĉon means one branch or a single branch

Esperanto has no indefinite article like English a/an. So often Esperanto simply uses the noun alone, or sometimes unu if the speaker wants to emphasize one.

So:

• branĉon = a branch / branch
• unu branĉon = one branch, one single branch

In this sentence, unu probably emphasizes that only one branch is being trimmed.

Its basic meaning is one.

Because Esperanto has no separate word for a/an, unu can sometimes feel similar to English a/an in certain contexts, but it usually adds some sense of one particular, one single, or one in number.

So here:

• mi tondas unu branĉon

most naturally suggests I trim one branch or I trim a single branch, not just I trim a branch in a completely neutral way.

The dictionary forms are:

• transplanti = to transplant
• kultivi = to cultivate
• tondi = to trim / shear / cut
• planto = plant
• branĉo = branch
• kaj = and
• mi = I
• ni = we
• unu = one
• la = the

A useful pattern:

• verbs are usually listed in -i form, the infinitive
• nouns end in -o

So:

• tondi → tondas
• branĉo → branĉon

The semicolon separates two closely related clauses:

• Ni transplantas kaj kultivas la planton
• mi tondas unu branĉon

It shows that the ideas are connected, but each clause has its own subject and verb structure.

A comma might also be seen in some writing, but the semicolon helps show the shift from we to I more clearly.

Yes, Esperanto has fairly flexible word order because the -n ending shows which noun is the object.

For example, Ni transplantas la planton is the normal order, but La planton ni transplantas is also grammatically possible. The second version gives extra emphasis to the plant.

Still, the sentence as given is the most neutral and natural order for learners:

• subject + verb + object

The letter ĉ is pronounced like English ch in church.

So:

• branĉon sounds roughly like BRAHN-chon
• branĉo = branch
• branĉon = branch as a direct object

A few pronunciation notes:

• a is like a in father
• o is a clear o sound
• the stress in Esperanto normally falls on the second-to-last syllable

So branĉon is stressed on bran: BRAN-ĉon.

Tondi usually means to trim, clip, shear, or cut back, especially with plants, hair, wool, hedges, and similar things.

So in this sentence, mi tondas unu branĉon suggests trimming or cutting off a branch, rather than a very general cut.

If you wanted a broader verb, Esperanto has other options, but tondi is a very natural choice for pruning or trimming.

Because Esperanto is highly systematic.

In this one sentence you can see several core patterns:

• -as = present tense verb
• -o = noun
• -n = direct object
• fixed pronouns like mi and ni
• simple connectors like kaj

That means once you learn the patterns, you can understand new sentences very quickly. For example:

• Mi kultivas planton = I cultivate a plant
• Ni tondas branĉon = We trim a branch
• Mi transplantas la planton = I transplant the plant

The sentence is a good example of how Esperanto builds meaning through regular grammar rather than lots of irregular forms.
