interjection
good answer!; that's right!; bullseye!
Polite interjection used to praise a correct answer, often in quiz-like or guessing contexts. The honorific ご adds a respectful tone.
「答えは江戸時代です」「ご名答！」
"The answer is the Edo period." "That's right!"
クイズで正解したら、先生が「ご名答」と言ってくれた。
When I got the quiz right, the teacher said, "Good answer!"
Combination of the honorific prefix ご (御) and 名答 (meitō), meaning 'excellent answer'. The exact historical derivation is uncertain, but it is a set phrase used to commend a correct response.
