Learn French: L'institution doit lire le rapport afin d'approuver la subvention. - The institution must read the report in order to approve the grant.

Both afin de and pour mean "in order to" and are followed by an infinitive verb. However, afin de is more formal. Because this sentence involves administrative vocabulary like institution, rapport, and subvention, the formal tone of afin de fits perfectly.

Why does afin de change to afin d' here?

The base expression is afin de, but because the following verb (approuver) starts with a vowel, the e in de is dropped (elided) to make pronunciation smoother. This gives us afin d'approuver.

Why is there no preposition between doit and lire?

Devoir (must / to have to) is a modal verb. Just like in English where we say "must read" and not "must to read", French modal verbs connect directly to the infinitive verb that follows them, without needing a preposition like à or de.

What exactly is a subvention?

In French, une subvention refers to a "grant" or "subsidy"—financial assistance usually given by a government or organization. While "subvention" exists in English, it's quite rare, but in French it's the standard, everyday word for this kind of funding.
