répondrai
Répondrai is a French verb form derived from répondre, meaning “to answer.” It represents the future simple (simple future) tense and is used to express an action that will take place later. In standard conjugation, the future stem for répondre is répondr-, and the endings are added as -ai, -as, -a, -ons, -ez, -ont. Therefore the first-person singular form is je répondrai, the second-person singular is tu répondras, the third-person singular is il répondra, and so on for the other persons: nous répondrons, vous répondrez, ils répondront.
In many written and spoken contexts, répondrai is closely linked to the idea of a forthcoming answer,
