Ako je rupa na zidu veća, morat ćemo zvati majstora.

Ako means if.

So Ako je rupa na zidu veća... means If the hole in the wall is bigger...

In Croatian, ako introduces a real or possible condition, just like if in English.

Je is the 3rd person singular present tense of biti (to be), so it means is.

Here, je links the subject rupa (hole) with the adjective veća (bigger):

• rupa je veća = the hole is bigger

Croatian often uses the present tense in the if-clause when English would also use present tense:

• Ako je rupa veća, ... = If the hole is bigger, ...

Rupa is in the nominative singular because it is the subject of the clause.

• rupa = hole
• rupa je veća = the hole is bigger

The adjective veća matches rupa because rupa is:

• feminine
• singular
• nominative

So:

• rupa → feminine singular nominative
• veća → feminine singular nominative comparative adjective

Because na zidu uses the locative case, which is used after na when it means on or at a location.

• na zid = onto the wall / movement toward the wall
• na zidu = on the wall / location

In this sentence, the hole is being described as located on the wall, not moving onto it, so Croatian uses:

• na zidu = on the wall

Also:

• zid = wall
• zidu = locative singular of zid

Yes, depending on the situation.

• na zidu = on the wall
• u zidu = in the wall

If you are talking about a visible opening or damage on the surface, na zidu can sound natural.

If you want to emphasize that the hole is inside or through the wall structure, u zidu may also be possible.

So the choice depends a bit on how the speaker imagines the hole.

Veća is the comparative form of velika (big), so it means bigger.

Basic pattern:

• velik / velika / veliko = big
• veći / veća / veće = bigger

Because rupa is feminine singular, the comparative must also be feminine singular:

• rupa je veća = the hole is bigger

This often implies comparison with what was expected, with another hole, or with a size that would still be manageable.

Morat ćemo means we will have to.

It is the future tense of morati (must / have to).

• moramo = we have to / we must now
• morat ćemo = we will have to

So the sentence means that this will become necessary in the future if the condition is true.

In standard Croatian, the future tense with verbs in -ti is usually formed by dropping the final -i of the infinitive and adding the auxiliary:

• morati
  • ćemo → morat ćemo

This is the normal standard form.

So:

• morat ću = I will have to
• morat ćemo = we will have to

You may sometimes see or hear nonstandard forms, but morat ćemo is the correct standard one.

It comes from ćemo, which is the 1st person plural future auxiliary.

So:

• ću = I will
• ćeš = you will
• će = he/she/it will
• ćemo = we will
• ćete = you (plural) will
• će = they will

That means morat ćemo already includes the subject we, so Croatian does not need to say mi unless it wants extra emphasis.

After morati (to have to), Croatian uses an infinitive:

• morat ćemo zvati = we will have to call

So the structure is:

• morati
  • infinitive

Examples:

• Moram ići. = I have to go.
• Morat ćemo čekati. = We’ll have to wait.
• Morat ćemo zvati majstora. = We’ll have to call a handyman / repairman.

Because majstora is the accusative singular form, used here as the direct object of zvati.

• majstor = nominative singular
• majstora = accusative singular

Since zvati means to call someone, the person being called is the direct object:

• zvati majstora = to call the handyman / repairman

This is especially common with masculine animate nouns, where the accusative often matches the genitive form.

Majstor literally means master/craftsman, but in everyday Croatian it often means:

• handyman
• repairman
• tradesman
• workman

In this sentence, it most likely refers to someone skilled who can fix damage in a wall, such as a builder, plasterer, or general repair person.

So zvati majstora is a very natural phrase meaning call someone to come fix it.

Yes, Croatian word order is fairly flexible.

The given order is natural and neutral:

• morat ćemo zvati majstora

But other orders can be possible for emphasis, for example:

• morat ćemo majstora zvati
• majstora ćemo morati zvati

However, not every rearrangement sounds equally neutral. The original sentence is the most straightforward and natural in ordinary speech.

Yes. This is a very normal Croatian pattern:

• Ako + present, future/main result

So:

• Ako je rupa na zidu veća, morat ćemo zvati majstora.

This corresponds closely to English:

• If the hole in the wall is bigger, we’ll have to call a handyman.

Other examples:

• Ako pada kiša, ostat ćemo doma. = If it rains, we’ll stay home.
• Ako bude kasno, uzet ćemo taksi. = If it’s late, we’ll take a taxi.

Yes. Croatian often omits subjects when they are already clear from the verb form.

So instead of saying:

• Mi ćemo morati zvati majstora

it is more natural to say:

• Morat ćemo zvati majstora

because ćemo already tells you the subject is we.

The sentence is already perfectly natural as given.

A fairly literal breakdown would be:

• Ako = if
• je = is
• rupa = hole
• na zidu = on the wall
• veća = bigger
• morat ćemo = we will have to
• zvati = call
• majstora = a handyman / repairman

So very literally:

If the hole on the wall is bigger, we will have to call a repairman.

More natural English would usually be:

If the hole in the wall is bigger, we’ll have to call a handyman.
