Il ponte rischia di crollare.

Rischia is the third-person singular present tense of rischiare (to risk).

Because the subject is il ponte (the bridge), Italian uses the he/she/it form:

• io rischio = I risk
• tu rischi = you risk
• lui/lei rischia = he/she risks
• il ponte rischia = the bridge risks / is at risk

So rischia agrees with ponte, which is singular.

After rischiare, Italian normally uses di + infinitive when another verb follows.

So:

• rischiare di crollare = to risk collapsing
• rischiare di perdere = to risk losing
• rischiare di cadere = to risk falling

This is a very common Italian pattern. In English, we often use to risk + -ing or to be at risk of + -ing, but Italian uses di + infinitive here.

Because rischia is already the main conjugated verb in the sentence.

In Italian, when one verb depends on another, the second verb is often left in the infinitive:

• vuole andare = he/she wants to go
• può partire = he/she can leave
• rischia di crollare = it risks collapsing

So crollare stays in its dictionary form because rischia carries the tense and agreement.

Not exactly.

Crollare means to collapse, especially for structures or things that give way:

• a bridge collapses
• a building collapses
• a wall collapses

Cadere means to fall in a more general sense:

• a person falls
• a glass falls
• leaves fall

So with ponte, crollare is the natural choice because a bridge does not just fall in the ordinary sense; it collapses.

Italian uses the definite article much more often than English.

Here, il ponte means the bridge. In a normal complete sentence, Italian usually needs the article before a singular countable noun like this.

Saying just Ponte rischia di crollare would sound incomplete or unnatural in standard Italian.

Not necessarily.

Rischia di crollare means the bridge is in danger of collapsing or could collapse. It describes a current risk, not necessarily an action already happening.

So the sentence suggests:

• the danger exists now
• the collapse may happen
• but the bridge may not be collapsing at this exact moment

If you wanted to say it is actually in the process of collapsing, you would usually need a different structure.

No. They are close, but not identical.

• rischia di crollare = it is at risk of collapsing
• sta per crollare = it is about to collapse

Rischia di crollare focuses on danger or possibility.
Sta per crollare suggests the collapse is very imminent.

So sta per crollare is stronger and more immediate.

No. Rischiare can also take a noun directly.

For example:

• rischia la vita = he/she risks his/her life
• rischiano tutto = they risk everything

But when the thing being risked is an action, Italian usually uses di + infinitive:

• rischia di cadere
• rischiano di perdere
• rischio di arrivare tardi

So in this sentence, di crollare is the normal pattern.

Because the normal Italian structure is:

subject + conjugated verb + di + infinitive

So:

• Il ponte = subject
• rischia = conjugated verb
• di crollare = infinitive phrase

This is the standard word order and sounds completely natural.

Yes, but the usual order is best for learners:

• Il ponte rischia di crollare.

Italian can sometimes move elements around for emphasis, but that is less neutral and often more literary or context-dependent. In ordinary speech and writing, the original order is the safest and most natural choice.

No. In Italian, chi is pronounced like kee, not like English chee.

So:

• rischia sounds roughly like REES-kya
• crollare sounds roughly like krol-LAH-re

Important points:

• schi in rischia has a hard sk sound
• gli is not involved here, so there is no special lli sound
• the rr in crollare is typically rolled or tapped, depending on the speaker

So rischia does not sound like English rich-ya.

No, not here.

Crollare is intransitive in this sentence, so it means to collapse itself. The subject il ponte is the thing that may collapse.

So the structure is:

• the bridge = subject
• risks
• collapsing

It does not mean the bridge is making something else collapse.
