Fresh
な adjective
New and fresh is fresh (has to be new if you want it to be fresh, after all).
This word is used to describe fresh vegetables, fish, air, and new ideas or experiences, but is not commonly used to describe freshly made food or drinks. This is because the word emphasizes the inherent freshness of the thing being described, rather than its recent production.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
魚屋さんに行って、新鮮なマグロを買ってきてちょうだい。
Can you go to a fish shop and get fresh tuna?
今日はちょっと山に行って新鮮な空気をすってきました。
Today, I went to a mountain and breathed some fresh air.
前の職場では、止めろと言われるまでいつも残業していたので、毎日五時に退社するのはとても新鮮です。
I always worked overtime at my last job until I was told to stop, so it’s very new to me to leave work at five o’clock every day.
