Learn French: Ils acceptent courageusement le mauvais résultat.

It means bravely or courageously, and it follows the standard rule for making adverbs. First, you take the feminine form of the adjective for brave (courageuse), and then you add the ending -ment to get courageusement.

Why is courageusement placed right after the verb?

In French, adverbs that describe how an action is done almost always go immediately after the conjugated verb (acceptent). In English, we often put them at the end of the sentence (They accept the result bravely), but French prefers to keep the adverb and verb close together.

Do the endings of acceptent and courageusement sound the same?

No, this is a very common trap! The -ent on the verb acceptent is silent because it is a third-person plural verb ending. However, the -ent inside the adverb ending -ment is pronounced.

I thought adjectives usually go after the noun. Why is it le mauvais résultat?

You are right that most adjectives follow the noun, but mauvais (bad) is an exception. It belongs to a small group of common adjectives describing goodness or badness (like bon and mauvais) that are placed before the noun.
