Le hasard change le score.

Because French usually needs an article before both the subject noun and the object noun.

• le hasard = chance / luck / random chance
• le score = the score

So the sentence structure is:

• Le hasard = subject
• change = verb
• le score = direct object

English sometimes drops articles where French keeps them, especially with general or abstract ideas.

In French, nouns are very often used with an article. A bare noun is much less common than in English.

So French prefers:

• le hasard
• le score

rather than just hasard or score

This is one of the big habits English speakers need to get used to: French often sounds more complete when a noun has an article.

Hasard is masculine, which is why it takes le:

• le hasard

If it were feminine, it would take la.

You generally have to learn the gender along with the noun:

• hasard → masculine
• score → masculine

Because this is the il/elle/on form of the verb changer in the present tense, and French verbs do not work like English verbs.

Here is the present tense of changer:

• je change
• tu changes
• il/elle/on change
• nous changeons
• vous changez
• ils/elles changent

So with le hasard (a third-person singular subject), the correct form is change.

A useful detail: several of these forms are spelled differently but sound the same.

No, not exactly.

French change is pronounced roughly like shahnzh.

A few important points:

• the ch in French is usually like sh
• the an is a nasal vowel, not a clear English an
• the final e is not pronounced
• the final sound is like the g in beige or measure, followed by the sound of zh

So it does not sound like the English word change, even though they look similar.

The word order is the normal French pattern:

• subject + verb + object

So:

• Le hasard = subject
• change = verb
• le score = object

This is the same basic order as in English, which makes the sentence relatively easy to recognize structurally.

Because French does not need an extra helping verb here. The main verb change already carries the meaning.

English can say things like:

• Chance changes the score
• Chance is changing the score
• Chance does change the score

But in French, change by itself is simply the present tense form of changer. No extra word is needed in this sentence.

Score is a word French uses as well, especially in sports, games, and competition contexts.

It is masculine:

• le score

This is a good example of a word that looks familiar to an English speaker, although the pronunciation in French is different.

Hasard is pronounced roughly like ah-zar.

A few details:

• the h is silent
• the first a is an open a sound
• the s is pronounced like z because it is between vowels
• the final d is usually silent

So it is not pronounced like an English speaker might guess from the spelling.

Yes, grammatically you could say:

• Un hasard change le score

But that changes the nuance.

• Le hasard often refers to chance in a general sense
• Un hasard would mean a chance event, a coincidence, or some random occurrence

So le hasard is the more natural choice if you are talking about chance as a general force or concept.

Often yes, but not always word-for-word in natural English.

French uses definite articles more often than English, so le score may sometimes be translated simply as the score, but in some contexts English might phrase things differently depending on what sounds natural.

The key grammar point is that French normally keeps the article:

• le score

even where English might be more flexible.
