Here's a breakdown:
* エチュード (etude): This is the Japanese word for "etude," a musical composition designed to develop a specific technical skill.
* イッシュ (ish): This is a Japanese pronunciation of the English word "ish," used to express something approximate or not definite.
* ショー (sho): This is a Japanese word meaning "show" or "performance."
* ナイス (naisu): This is a Japanese pronunciation of the English word "nice."
Therefore, the phrase translates to something like "etude-ish show, nice" or "a kind of etude performance, nice."
