Questions & Answers about ani wa kenkou no tame ni mainichi hashirimasu.

Why is 兄 marked with は instead of が?

The particle は marks “兄” as the topic of the sentence—what we are talking about—whereas が would mark it as the subject presenting new or contrastive information. Since you’re stating a habitual fact about your brother (he runs every day), は is the natural choice.

What does 健康のために mean, and why is the particle の used after 健康?

健康のために literally means “for the sake of health.” Here, の turns 健康 (health) into a modifier of ため, making the phrase “the sake of health.” Without の, you couldn’t link the noun 健康 to ため properly; you’d need something like 健康に but that would mean “in a healthy way,” not “for health.”

What role does ために play in this sentence?

ために expresses purpose or reason. In this case, it tells us why your brother runs: for the benefit of his health. The structure is [noun] + の + ために to indicate “for the sake of [noun].”

Why is there no particle after 毎日?
