La stratégie dépend du hasard.

Because stratégie is a feminine singular noun in French, so it takes la.

• la stratégie = the strategy
• les stratégies = the strategies

Like all French nouns, stratégie has grammatical gender, and that gender does not always match anything logical in English. You simply learn the noun together with its article.

A useful pattern: many nouns ending in -ie are feminine, and stratégie is one of them.

Because the French verb is dépendre de. French and English often use different prepositions with the same idea.

So:

• dépendre de quelque chose = to depend on something
• Ça dépend de toi. = That depends on you.
• Tout dépend de la situation. = Everything depends on the situation.

It is best to learn dépendre de as one unit, not to translate the preposition word for word.

Because hasard is a masculine singular noun: le hasard.

After de, French contracts:

• de + le = du

So:

• dépendre de le hasard → dépendre du hasard

That makes du here a contraction, not a separate word you choose freely.

So:

• de hasard = incorrect
• de le hasard = incorrect
• du hasard = correct

Because hasard takes le, not l':

• le hasard
• not l'hasard

This is because hasard begins with an aspirated h (h aspiré), which blocks elision. In other words, even though the word begins with h, French treats it more like a consonant for this purpose.

So you get:

• le hasard
• du hasard
• ce hasard

not:

• l'hasard
• de l'hasard
• cet hasard

No. In this sentence, du does not mean some. It is simply the contraction of de + le.

So here:

• du hasard = de le hasard

That is different from cases where du is a partitive article meaning some.

In La stratégie dépend du hasard, du is there because the verb uses de, and the noun is le hasard.

Because French usually keeps an article where English often leaves one out, especially with general or abstract nouns.

So French naturally says:

• dépend du hasard

even though English may say:

• depends on chance
• depends on luck

This is very common in French. Do not assume English article usage will match French article usage.

Hasard usually means chance, randomness, or luck, depending on context.

In this sentence, it suggests that the strategy relies on something unpredictable rather than something fully controlled.

So the nuance is often closer to:

• chance
• random chance
• luck

It does not necessarily mean good luck. It can simply mean that outcomes are left to chance.

Because the subject is la stratégie, which is third-person singular.

The infinitive is dépendre = to depend.

Present tense:

• je dépends
• tu dépends
• il/elle/on dépend
• nous dépendons
• vous dépendez
• ils/elles dépendent

Since la stratégie is like elle, the correct form is dépend.

The accents are part of the correct spelling and help show pronunciation.

• é in stratégie is a clear ay/e sound
• è in dépend is a more open e sound

A rough pronunciation guide:

• stratégie ≈ stra-tay-zhee
• dépend ≈ day-pahn (with a nasal vowel at the end)

The accents are not optional in standard written French.

A rough English-friendly pronunciation is:

la stra-tay-zhee day-pahn du a-zar

A more precise IPA version is:

[la stʁa.te.ʒi de.pɑ̃ dy a.zaʁ]

A few pronunciation notes:

• stratégie ends with the zh sound, like s in measure
• dépend ends in a nasal vowel, so the final n is not pronounced separately
• in hasard, the h is not pronounced
• but because it is an h aspiré, there is normally no liaison before it

In normal French, this sentence is most naturally:

La stratégie dépend du hasard.

That is the standard order:

• subject: La stratégie
• verb: dépend
• complement: du hasard

You might see other word orders only for special emphasis or in more literary styles, but for everyday use, this is the normal and correct pattern.
