Questions & Answers about watashi wa natsuyasumi o tanoshimi ni shite imasu.

What do the particles は, を, and に do in this sentence?

• は marks the topic: 私 is “as for me.”
• を marks the thing you’re looking forward to: 夏休み is the direct object of 楽しみにする.
• に is part of the pattern N(oun) + に + する (“to make something into …”). Here it’s inside the set phrase 楽しみにする (“to look forward to”).

Why is 夏休み marked with を and not が?

• With the expression Nを楽しみにする, the thing anticipated takes を.
• There’s a different, equally common pattern where you use が: Nが楽しみだ (e.g., 夏休みが楽しみです). That one uses the noun 楽しみ with だ/です, not する.

What’s the difference between 楽しみ, 楽しむ, and 楽しい? Why use 楽しみ here?

• 楽しみ: noun, “a pleasure; something to look forward to.” Used in 楽しみにする.
• 楽しむ: verb, “to enjoy.” Example: 夏休みを楽しむ = “enjoy summer break.”
• 楽しい: i-adjective, “fun; enjoyable.” Example: 夏休みは楽しい = “Summer break is fun.”
• You can’t say 楽しいにする. If you want “make (something) fun,” it’s 楽しくする (different meaning). For “look forward to,” use the set phrase with the noun: 楽しみにする.
