Questions & Answers about sensei wa gakusei ni mainichi nihongo o hanasaseru.

What is the causative form 話させる, and how is it formed?

To create the causative of the godan verb 話す (to speak), replace the final -す with -させる, giving 話させる. The causative means “to make/let someone speak.”

Why is 学生 marked with に instead of を in this sentence?

In a causative sentence, the person who is made to do something (the causee) is usually marked with に when the action is indirectly caused (e.g., by ordering or allowing). If you directly force someone, you could use を, but that sounds harsh. Here the teacher is ordering, so 学生に is natural.

Who is the grammatical subject, and what role does は play here?

The subject marked by は is 先生 (the teacher). The particle は highlights 先生 as the topic/agent performing the causative action.

What does 日本語を indicate in this context?

日本語を marks the direct object of 話す—the language being spoken. Even in the causative, the underlying verb’s object retains its を marker.

What is the function and placement of the adverb 毎日?
