Questions & Answers about kyonen no natsu no ibento de wa, kantan na koto o shite keihin o futatsu mo moraimashita.

Why is の used twice in 去年の夏のイベント? What does each の do?

Both の particles here are doing the same job: they link nouns together, like an apostrophe‑s or “of” in English.

• 去年の夏 = “the summer of last year” / “last summer”
  → 去年 (last year) is modifying 夏 (summer).

• 夏のイベント = “the event of (that) summer” / “the summer event”
  → 夏 (summer) is modifying イベント (event).

Put together:

• 去年の夏のイベント
  Literally: “the event of the summer of last year”
  Naturally: “the event last summer”.

Japanese often chains several nouns with の like this; it’s very normal and not considered redundant.

What is the difference between イベントで and イベントでは here? Why add は after で?

で marks the place where an action happens:

• イベントで = “at the event”.

Adding は after で makes イベントで the topic and often adds a slight contrast, like “as for at the event” or “at the event (at least)…”.

So:

• イベントで = neutral “at the event”.
• イベントでは = “at the event, (speaking about that situation)…”
  and can imply contrast with other times/places, e.g.
  “At the event (unlike usual), I got as many as two prizes.”

This is called “particle stacking”: で (location) + は (topic/contrast).
