Verb aspects are really important in Japanese because they help show when actions happen and what kind they are. Here’s why they’re useful:

1. Completed vs. Ongoing Actions:

   • Completed Action: When you use the past tense, like 食べた (tabeta - "ate"), it means the action is done.
   • Ongoing Action: The present continuous form, like 食べている (tabete iru - "is eating"), shows that the action is happening right now.

2. Contextual Clarity:

   • For example, "彼は本を読んでいる" (Kare wa hon o yonde iru - "He is reading a book") tells us that he is in the middle of reading.
   • On the other hand, "彼は本を読んだ" (Kare wa hon o yonda - "He read a book") tells us that he finished reading.

3. Engaging Conversations:

   • Knowing these aspects makes your conversations clearer. It helps you express yourself better and communicate more effectively.
