流石

• 読み: さすが

意味

As expected of you — a compliment acknowledging that someone has performed up to or beyond their known high standard.

While さすが itself is a standard Japanese word, the kanji form 流石 is an ateji (phonetic kanji assignment) commonly used online and in text for a slightly more emphatic or literary feel. It conveys admiration with an element of 'I knew you could do it.' Used both sincerely and sometimes with a hint of friendly sarcasm. Very popular on social media and in gaming contexts.

例文

1. 流石だね、一発で解けるなんて。

3. このクオリティは流石としか言えない。

起源と歴史

The word さすが dates back to classical Japanese. The kanji 流石 is an ateji derived from a Chinese story about a man who mixed up 枕石漱流 (pillow on stone, rinse in stream) but stubbornly defended his mistake — hence 流石 came to mean 'as expected, impressive persistence.' The kanji form gained renewed popularity on the internet.
