Depositei o rendimento após a amortização.

Portuguese often leaves out the subject pronoun when the verb ending already makes it clear who the subject is.

• Depositei = I deposited
• The ending -ei shows 1st person singular in the pretérito perfeito (simple past)

So Depositei o rendimento... naturally means I deposited the income/return... without needing eu.

You could say Eu depositei o rendimento..., but that usually adds emphasis, contrast, or clarity.

Depositei is the pretérito perfeito do indicativo.

In this sentence, it shows a completed past action:

• deposito = I deposit / I am depositing
• depositei = I deposited

So the speaker is talking about one finished action in the past.

The infinitive is depositar.

Yes, it is a regular -ar verb.
Its past form here follows the normal pattern:

• eu depositei
• tu depositaste
• ele/ela depositou
• nós depositámos
• vós depositastes
• eles/elas depositaram

So if you know regular -ar verbs, this form is predictable.

Rendimento can have several related meanings depending on context. Common ones include:

• income
• return or yield (especially financial)
• performance or output

In a financial sentence like this, o rendimento often means something like:

• the return
• the yield
• the income produced

So even if the translation has already been given to you, it is useful to know that rendimento is a flexible word and not always just one thing.

Portuguese uses definite articles more often than English.

Here:

• o = the
• rendimento is a masculine singular noun

So o rendimento literally means the income/return.

In Portuguese, using the article often sounds more natural when referring to a specific known thing in context.

Após means after.

It is very close in meaning to depois de, but após often sounds:

• a bit more formal
• more written or administrative
• common in financial, legal, or official language

So:

• após a amortização
• depois da amortização

Both can mean after the amortization/repayment, but após sounds slightly more formal.

Because amortização is a feminine singular noun.

So it takes:

• a = the (feminine singular)

That gives:

• a amortização

This is just normal noun gender agreement:

• o rendimento → masculine
• a amortização → feminine

In financial contexts, amortização usually refers to:

• repayment of debt
• paying off part of a loan
• amortization of a financial amount

Depending on context, it may refer to:

• a mortgage repayment
• partial repayment of capital
• scheduled loan reduction

So in European Portuguese, it is a standard finance word and is very common in banking, loans, and accounting.

Yes. Portuguese allows some flexibility.

You can say:

• Depositei o rendimento após a amortização.
• Após a amortização, depositei o rendimento.

Both are correct.

The second version puts more focus on the time sequence: After the amortization, I deposited the return/income.

The original version is very natural and neutral.

No. It stays após a amortização.

That is because após does not combine with the article the way some prepositions do.

For example:

• de + a = da
• em + a = na
• a + a = à

But após does not contract like that, so you simply say:

• após a amortização

not após à amortização.

Yes, absolutely.

• após a amortização
• depois da amortização

Both are correct.

Notice the difference in structure:

• após + a amortização
• depois de + a amortização = depois da amortização

So with depois de, the contraction happens:

• de + a = da

This is a very common point for learners.

It overlaps with income, but it is broader.

In Portugal, rendimento can refer to:

• salary-related income
• investment return
• rental income
• productivity or performance

So English speakers should not assume it always means only income in the narrow salary sense.

For example:

• rendimentos do trabalho = employment income
• rendimento de um investimento = return on an investment
• bom rendimento = good performance

In European Portuguese, several vowels are reduced, so the sentence may sound less fully pronounced than an English speaker expects.

A rough guide:

• Depositei: the first e is often weak
• rendimento: some unstressed vowels are reduced
• após: stress is on the second syllable
• amortização: stress falls on -ção

A simple stress guide:

• depo-si-TEI
• rendi-MEN-to
• a-PÓS
• amor-tiza-ÇÃO

If you are learning European Portuguese specifically, listening to native audio is especially important because spelling and actual pronunciation can differ quite a lot.

Yes, but it sounds somewhat formal or financial.

Words like:

• depositei
• rendimento
• amortização
• após

all fit well in banking, accounting, investment, or official discussions.

In casual conversation, a speaker might choose simpler wording depending on context. But as a finance-related sentence, it sounds perfectly natural in European Portuguese.

Yes. Both words are common in financial language.

• rendimento can suggest returns, income, or yield
• amortização is strongly associated with loans, repayments, accounting, and finance

So even though the grammar is straightforward, the vocabulary gives the sentence a technical or professional tone.
