Zaista te nisam htjela povrijediti.

Te means you as a direct object, so in this sentence it is you in hurt you.

Why not ti?

• ti = you as the subject
• te = you as the unstressed direct object form

So:

• Ti nisi... = You didn’t...
• Nisam te... = I didn’t ... you

A fuller, stressed form would be tebe, but Croatian normally uses the short clitic te here.

Because the speaker is female.

In Croatian past tense, the main verb agrees with the subject in gender and number. The subject ja is omitted, but the form htjela tells you the speaker is a woman.

• nisam htjela = I didn’t want / I didn’t mean to (female speaker)
• nisam htio = the same thing said by a male speaker

This is very normal in Croatian: even if I is not stated, the verb form can still show gender.

This is the Croatian past tense, built with:

• the auxiliary biti in the present tense
• plus the l-participle of the main verb

Here:

• nisam = I am not in form, but used as the negative auxiliary I did not / have not
• htjela = past participle of htjeti (to want)

So nisam htjela literally works like I didn’t want, but in context it often means I didn’t mean to.

Because Croatian often drops subject pronouns when they are already clear from the verb form.

In this sentence, nisam already tells you the person is I, and htjela tells you the speaker is feminine. So ja is unnecessary.

You could say Ja te nisam htjela povrijediti, but that would add extra emphasis, like I really didn’t want to hurt you.

Because te is a clitic, and Croatian clitics usually go in the second position of the clause.

So in:

Zaista te nisam htjela povrijediti.

• Zaista is the first stressed word
• te comes right after it

That placement is very natural in Croatian.

Compare:

• Nisam te htjela povrijediti.
• Zaista te nisam htjela povrijediti.

In both cases, te appears in the typical clitic position.

Povrijediti is the infinitive, meaning to hurt, to injure, or emotionally to hurt someone’s feelings, depending on context.

Here it most naturally means emotional hurt: to hurt you.

It follows htjeti, because Croatian commonly uses:

• htjeti + infinitive = to want to do something

So:

• htjela povrijediti = wanted/meant to hurt

Because povrijediti is perfective and fits a single completed act or result: to hurt someone.

That matches the idea here: the speaker is saying they did not intend to cause that hurt.

By contrast:

• vrijeđati usually means to insult or to offend, often with a repeated or ongoing sense
• povrjeđivati would be the imperfective partner meaning to be hurting / to hurt repeatedly

So povrijediti is the best choice for I didn’t want to hurt you as one event.

Zaista means really, truly, or genuinely.

It adds sincerity and emphasis:

• Nisam te htjela povrijediti. = I didn’t want to hurt you.
• Zaista te nisam htjela povrijediti. = I really / truly didn’t want to hurt you.

It sounds a little more earnest and reassuring.

Yes, in many situations you could.

For example:

• Stvarno te nisam htjela povrijediti.
• Zaista te nisam htjela povrijediti.

Both can mean I really didn’t want to hurt you.

The difference is mostly style:

• stvarno = very common, conversational
• zaista = also common, but can sound a bit more deliberate or sincere
• doista = a bit more formal or literary in some contexts

It can be understood as both, depending on context.

Literally, nisam htjela povrijediti is I didn’t want to hurt. But in English, the most natural translation in many emotional situations is often I didn’t mean to hurt you.

So the Croatian sentence can express lack of intention, not just lack of desire.

That is why it may sound softer and more apologetic than a simple word-for-word translation suggests.

Yes, Croatian word order is flexible, but the emphasis changes.

For example:

• Zaista te nisam htjela povrijediti. = emphasis on really / truly
• Nisam te htjela povrijediti. = neutral
• Ja te nisam htjela povrijediti. = emphasis on I
• Nisam te zaista htjela povrijediti. = possible, but it sounds a little different in focus

The version you have is very natural if the speaker wants to sound especially sincere.
