Mi akceptos ĝin, kondiĉe ke la tarifo restos sama.

Kondiĉe ke means provided that, on condition that, or as long as.

It introduces a condition:

• Mi akceptos ĝin, kondiĉe ke la tarifo restos sama.
• I will accept it, provided that the rate stays the same.

A helpful way to remember it:

• kondiĉo = condition
• -e makes it adverbial: conditionally / on the condition
• ke = that

So the whole phrase literally feels like on the condition that.

Akceptos is the future tense of akcepti (to accept).

Esperanto verb endings are very regular:

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

So:

• mi akceptas = I accept / I am accepting
• mi akceptos = I will accept

In this sentence, the speaker is talking about a future decision, so -os is natural.

Because ĝin is the direct object form.

In Esperanto, the -n ending marks the direct object. Compare:

• ĝi = it
• ĝin = it (as the thing being affected by the verb)

Here, it is the thing being accepted, so it must be ĝin:

• Mi akceptos ĝin = I will accept it

This is the same pattern as:

• Mi vidas lin = I see him
• Ŝi aĉetis la libron = She bought the book

Restos is future indicative: will remain / will stay.

In this sentence, the condition is stated as a real condition, not as a hypothetical one. Esperanto often uses the normal tense after kondiĉe ke:

• ... kondiĉe ke la tarifo restos sama = provided that the rate remains the same

A native English speaker may expect something like a special subjunctive or conditional form, but Esperanto usually keeps things straightforward here.

Compare:

• Se li venos, mi iros. = If he comes, I will go.
• Kondiĉe ke la tarifo restos sama, mi akceptos ĝin. = Provided that the rate stays the same, I will accept it.

Restus would sound more hypothetical or less direct in many contexts.

Resti means to remain, to stay, or to continue to be.

So:

• la tarifo restos sama = the rate will remain the same

It does not mean to rest in the English sense of relaxing. That is a common false-friend issue for English speakers.

Examples:

• Li restis hejme. = He stayed at home.
• La prezo restas alta. = The price remains high.

Sama is an adjective meaning same.

It describes tarifo, which is a singular noun, so the adjective stays singular too:

• la tarifo = the rate
• sama = same

Esperanto adjectives end in -a and agree with nouns in number and case when needed.

Examples:

• la sama tarifo = the same rate
• la samaj tarifoj = the same rates
• mi vidas la saman tarifon = I see the same rate

In your sentence, sama is a predicate adjective after restos, so there is no -n.

Yes, but the nuance changes a little.

• se = if
• kondiĉe ke = provided that / on condition that

So:

• Mi akceptos ĝin, se la tarifo restos sama.
• Mi akceptos ĝin, kondiĉe ke la tarifo restos sama.

Both are grammatical, but kondiĉe ke sounds more formal and more explicit about the condition. It suggests that this condition is an important requirement.

The comma separates the main clause from the conditional clause.

• Mi akceptos ĝin = main clause
• kondiĉe ke la tarifo restos sama = subordinate clause

Esperanto often uses commas quite clearly to separate clauses, especially when a phrase like kondiĉe ke introduces extra information.

You may also see the sentence with the clauses reversed:

• Kondiĉe ke la tarifo restos sama, mi akceptos ĝin.

That is also correct.

La is the definite article, meaning the.

Using la tarifo suggests that a specific rate/tariff is already known from the context. For example, both speaker and listener already know which rate is being discussed.

• la tarifo = the rate
• tarifo = a rate / rate in general

In many real situations, the definite article is natural because the speaker means a particular agreed or mentioned tariff.

Yes. Esperanto word order is fairly flexible, as long as the sentence stays clear.

These are all natural:

• Mi akceptos ĝin, kondiĉe ke la tarifo restos sama.
• Kondiĉe ke la tarifo restos sama, mi akceptos ĝin.

The first version starts with the main statement and then adds the condition. The second starts with the condition and may sound a bit more emphatic.

A rough pronunciation guide:

• Mi = mee
• akceptos = ak-TSEP-tos
• ĝin = jeen with ĝ like the j in jam
• kondiĉe = kon-DEE-che
• ke = keh
• la = lah
• tarifo = ta-REE-fo
• restos = RES-tos
• sama = SAH-ma

A more approximate full reading:

mee ak-TSEP-tos jeen, kon-DEE-che keh lah ta-REE-fo RES-tos SAH-ma

A few sound notes:

• ĉ sounds like ch in church
• ĝ sounds like j in judge
• Stress in Esperanto is always on the second-to-last syllable:
  • akCEPtos
  • konDIĉe
  • taRIfo
  • REStos
  • SAma

Tarifo means tariff, rate, or price schedule, depending on context.

It is a normal Esperanto word, especially in business, transport, utilities, official pricing, and similar contexts.

Depending on the situation, English might translate it as:

• rate
• tariff
• fee schedule
• pricing

So the Esperanto word is broader than just one English option. The exact English translation depends on context.

Yes, it is perfectly natural and grammatical.

It sounds like something you might say in a formal, business, or practical context, especially when accepting an offer under a stated condition.

Its structure is very typical:

• main statement
• followed by a condition introduced by kondiĉe ke

So for a learner, this is a very useful model sentence.
