Neću ti zamjeriti; iskrenost je važna kad si nesigurna.

Neću is the 1st person singular future negative form, meaning I will not / I won’t.

It comes from the verb htjeti (to want, but also used as a future auxiliary). In Croatian, the negative future forms are written as single words:

• neću = I won’t
• nećeš = you won’t
• neće = he/she/it won’t

So Neću ti zamjeriti means I won’t hold it against you.

A useful comparison:

• Zamjerit ću = I will hold it against...
• Neću zamjeriti = I will not hold it against...

Ti here means to you and is in the dative case.

The verb zamjeriti commonly works with a person in the dative:

• zamjeriti nekome nešto = to hold something against someone

So in this sentence:

• ti = to you
• the thing being held against the person is understood from context

In other words, Neću ti zamjeriti literally works like I will not hold [it] against you.

It is simply left out because it is understood from context.

Croatian often omits words that are obvious. The full structure would be something like:

• Neću ti to zamjeriti. = I won’t hold that against you.

But if everyone already knows what that is, Croatian very naturally leaves it out.

Because after neću, Croatian uses the infinitive to form the future.

So the pattern is:

• neću + infinitive

Examples:

• Neću doći. = I won’t come.
• Neću zaboraviti. = I won’t forget.
• Neću ti zamjeriti. = I won’t hold it against you.

Here, zamjeriti is the infinitive form.

This is a matter of aspect, which is very important in Croatian.

• zamjeriti = perfective
• zamjerati = imperfective

In simple terms:

• zamjeriti focuses on a single completed reaction: to take something amiss / to hold something against someone
• zamjerati suggests an ongoing, repeated, or habitual action

So:

• Neću ti zamjeriti. = I won’t hold it against you.
• Neću ti zamjerati. = I won’t keep holding it against you / I won’t be reproaching you for it.

In this sentence, zamjeriti fits well because it refers to a specific situation.

Because iskrenost is the subject, and je važna means is important.

Breakdown:

• iskrenost = honesty
• je = is
• važna = important

So:

• Iskrenost je važna. = Honesty is important.

This is a normal Croatian sentence with the verb to be.

Because it agrees with iskrenost, which is a feminine noun.

In Croatian, adjectives must agree with the noun in gender, number, and case.

Here:

• iskrenost is feminine singular
• so the adjective is važna, also feminine singular

Compare:

• plan je važan = the plan is important
• odluka je važna = the decision is important
• pitanje je važno = the question is important

A useful thing to remember: many nouns ending in -ost are feminine, including iskrenost.

Si is the 2nd person singular present form of biti (to be) in its short, unstressed form.

So:

• si = are
• kad si nesigurna = when you are unsure

The full form is jesi, but Croatian usually uses the short clitic form si in normal sentences.

Compare:

• Ti si umorna. = You are tired.
• Kad si nesigurna... = When you are unsure...

Because Croatian usually omits subject pronouns unless they are needed for emphasis or contrast.

So the normal version is:

• kad si nesigurna = when you are unsure

The pronoun ti is not necessary, because si already tells you the subject is you.

If you said kad ti si nesigurna, it would sound unnatural in standard Croatian.

For emphasis, Croatian would more naturally do something like:

• kad si ti nesigurna = when you are unsure

But in this sentence, plain kad si nesigurna is the natural choice.

Because the speaker is addressing a female singular person.

• nesigurna = unsure, feminine singular
• nesiguran = unsure, masculine singular

So this sentence is specifically directed to a woman or girl.

If speaking to a man, it would be:

• Neću ti zamjeriti; iskrenost je važna kad si nesiguran.

The prefix ne- simply negates the adjective:

• sigurna = sure, confident
• nesigurna = unsure, insecure

They are clitics: short unstressed words that tend to appear in a fixed position, usually near the beginning of their clause.

In this sentence:

• ti in Neću ti zamjeriti
• je in iskrenost je važna
• si in kad si nesigurna

Croatian clitic placement can feel unusual to English speakers, because English does not really work this way.

For now, the useful beginner rule is:

• these short forms usually cannot be stressed
• they usually appear early in the clause
• their position is not completely free

So Neću ti zamjeriti sounds natural, while something like Neću zamjeriti ti does not.

Yes.

• kad = when
• kada = when

They mean the same thing here. Kad is very common and natural in everyday speech, while kada can sound a little more formal or slightly more explicit depending on context.

So both are fine:

• kad si nesigurna
• kada si nesigurna

The semicolon links two closely related ideas:

• Neću ti zamjeriti
• iskrenost je važna kad si nesigurna

It shows that the second part explains or supports the first.

In normal writing, you might also see a comma or a full stop instead, depending on style:

• Neću ti zamjeriti. Iskrenost je važna kad si nesigurna.
• Neću ti zamjeriti, iskrenost je važna kad si nesigurna.

The semicolon just gives a slightly cleaner separation between two connected clauses.
