The differences between '好き' (suki) and '愛する' (aisuru) are really interesting! Both words can mean "to like" or "to love," but they are used in different ways and carry different feelings.

Suki (好き)

1. What It Means:

   • 'Suki' shows that you like something or someone. It's often used for things, activities, or even people you enjoy or admire.
   • Example:
     • 私は寿司が好きです。 (Watashi wa sushi ga suki desu.) – "I like sushi."
     • This means you enjoy sushi, but it doesn’t show a deep emotional connection.

2. When to Use It:

   • You can use 'suki' casually. It works well when talking about hobbies, food, animals, or friends you care about in a friendly way.

Aisuru (愛する)

1. What It Means:

   • On the other hand, 'aisuru' means a much stronger kind of love. It shows a deep emotional bond and is usually reserved for romantic partners, family, or things you are very passionate about.
   • Example:
     • 私は彼を愛しています。 (Watashi wa kare o aishiteimasu.) – "I love him."
     • Here, 'aisuru' shows a strong feeling and commitment to that person.

2. When to Use It:

   • You don’t use 'aisuru' lightly. It’s more serious and formal. It’s best for talking about deep feelings, like love for a partner or cares about family.

Summary of Differences

• Feeling: 'Suki' feels light and friendly, while 'aisuru' is heavy with deep emotions.
• When to Use: Use 'suki' for everyday likes and interests; save 'aisuru' for serious relationships and strong love.

By understanding these differences, you can communicate better in Japanese and express your feelings in the right way!
