Ovaj termin mi ne odgovara, jer radim do šest.

Because ovaj means this, and it has to agree with termin in gender, number, and case.

• termin is masculine singular
• here it is the subject of the sentence, so it is in the nominative
• therefore the correct form is ovaj

So:

• ovaj termin = this appointment / this time slot

You would use different forms with different nouns, for example:

• ova knjiga = this book
• ovo vrijeme = this time / this weather

In this sentence, termin means something like:

• appointment
• time slot
• scheduled time
• meeting time

It does not usually mean a grammar term or technical term here. In everyday Croatian, termin is very commonly used for a scheduled time for something, for example:

• a doctor’s appointment
• a meeting slot
• a lesson time
• a reservation time

So ovaj termin is basically this scheduled time.

Mi here means to me.

The verb odgovarati in this meaning works like to suit / to be convenient for someone. So Croatian expresses the person as an indirect object in the dative:

• To meni odgovara. = That suits me.
• To mi odgovara. = That suits me.

So:

• Ovaj termin mi ne odgovara literally means This time slot does not suit me

The short form mi is very common in normal speech.

Because the subject is ovaj termin, not I.

In English, we often say:

• This time doesn’t work for me
• This appointment doesn’t suit me

Croatian uses the same idea:

• Ovaj termin = the thing doing the suiting
• mi = to me
• ne odgovara = does not suit

So the verb is in 3rd person singular:

• odgovara = it suits

If you said odgovaram, that would mean I answer or I am suitable, depending on context, which is not what this sentence means.

No. Odgovarati has a few common meanings, and that can confuse learners.

Very common meanings are:

1. to answer / reply

   • Odgovaram na poruku. = I am replying to the message.

2. to suit / be convenient

   • Ovaj termin mi odgovara. = This time suits me.

3. sometimes to correspond to / match

So in this sentence, it clearly means to suit / be convenient.

Yes, but it changes the feel a little.

• mi = short unstressed form, the most natural choice in ordinary sentences
• meni = full form, often used for emphasis, contrast, or clarity

Compare:

• Ovaj termin mi ne odgovara. = neutral, natural
• Ovaj termin meni ne odgovara. = this time doesn’t suit me specifically

So mi is the normal version here.

Because Croatian has a group of short words called clitics, and they tend to go near the beginning of the clause, usually in the second position.

In this sentence:

• Ovaj termin = first unit
• mi = clitic, so it comes right after that unit
• ne odgovara = rest of the predicate

So:

• Ovaj termin mi ne odgovara.

This word order sounds natural in Croatian.

Jer means because.

So the second part of the sentence gives the reason:

• jer radim do šest = because I work until six

A very common alternative is zato što:

• Ovaj termin mi ne odgovara, jer radim do šest.
• Ovaj termin mi ne odgovara zato što radim do šest.

Both are correct. Jer is short and very common.

Because jer introduces a reason clause, and in Croatian it is normally separated by a comma.

So:

• Ovaj termin mi ne odgovara, jer radim do šest.

This is standard punctuation.

Radim is the 1st person singular form of raditi = to work.

It means:

• I work
• I am working (depending on context)

Since the subject I is understood from the verb ending, Croatian does not need to say ja here.

So:

• radim = I work

If you added ja, it would usually give extra emphasis:

• ...jer ja radim do šest.

But the neutral version is just radim.

Do means until / up to, and šest means six.

So:

• radim do šest = I work until six

This usually refers to time on the clock. In everyday speech, Croatian often leaves out the word sati:

• do šest = until six
• do šest sati = until six o’clock

Both are possible, but do šest is very natural and common.

In this kind of sentence, yes, very often.

When speaking about time, Croatians often simply say the number:

• u pet = at five
• do šest = until six
• oko osam = around eight

If needed, you can make it more explicit:

• radim do šest sati = I work until six o’clock

But the shorter version is usually enough.

Yes. Croatian usually drops personal subject pronouns when the verb already shows who the subject is.

So:

• radim already tells you it means I work

That is why the sentence does not need ja.

Croatian does this very often:

• Radim danas. = I’m working today.
• Ne mogu. = I can’t.
• Dolazim kasnije. = I’m coming later.

Yes. A useful literal breakdown is:

• Ovaj termin = this time slot / this appointment
• mi = to me
• ne odgovara = does not suit / is not convenient
• jer = because
• radim = I work
• do šest = until six

So a very literal version is:

• This appointment to me does not suit, because I work until six.

That literal structure helps explain why Croatian uses mi and odgovara the way it does.

It is not the most natural word order.

Because mi is a short clitic, Croatian strongly prefers it near the beginning of the clause:

• Ovaj termin mi ne odgovara. ✅ natural
• Ovaj termin ne odgovara mi. possible in special emphasis, but not the normal choice

So learners should generally use:

• Ovaj termin mi ne odgovara.

Ne is separate. It is the negative particle used to negate the verb.

• odgovara = suits / is convenient
• ne odgovara = does not suit / is not convenient

This is very common in Croatian:

• radim = I work
• ne radim = I do not work

So ne is not part of the verb itself; it is written separately.
