Questions & Answers about watashi wa toshokan de shukudai o hayame ni sumasemasu.

What does the particle は do here, and is 私 necessary?

• は marks the topic: “As for me…”
• 私 can be omitted if context makes it clear who is speaking: 図書館で宿題を早めに済ませます。
• Using が instead shifts emphasis to the subject (“I, and not someone else”): 私が図書館で宿題を早めに済ませます。
• You can also topicalize the object: 宿題は図書館で早めに済ませます。 (“As for the homework…”)

Why is it 図書館で and not 図書館に?

• で marks the place where an action happens (location of activity).
• に marks destination (with motion verbs) or location of existence (with いる/ある).
• Examples:
  • 図書館で勉強します。 (study at the library)
  • 図書館に行きます。 (go to the library)
  • 図書館にいます。 (be at the library)

What’s the nuance of 早めに compared with 早く?

• 早めに = “on the early side,” “earlier than usual/expected.” It implies choosing a time earlier than the reference point.
• 早く is the adverb of 早い and can mean “early” (time) or “quickly.” 早く済ませます can be heard as “finish quickly,” which is ambiguous.
• 早めに removes that ambiguity and focuses on earliness relative to a usual/expected time.

Why does 早め take に?
