ノック
ノック · nokku · JLPT N3 · noun
knock
🚪✊ Borrowed from English knock: no-k-ku = knock, with a Japanese ku ending
Japanese took the English word knock, so ノック is both a knock on a door and, in baseball, fielding practice where a coach knocks balls to the fielders (fungo). The small ッ is the short stop before the k sound in knock.
