説明
Use "the fewest" with countable plural nouns like "students," "books," and "mistakes." Use "the least" with uncountable nouns like "time," "water," and "salt."
In "This class has the fewest students in the school," "this class" is the thing we compare, "has" shows possession, and "the fewest students" means the smallest number of students. English chooses the form by the noun type, but Japanese often uses the same idea, like "いちばん少ない," for both. In "We have the least time today," "time" cannot be counted one by one, so "least" is correct.
「the fewest」は、students, books, mistakes のような数えられる複数名詞と一緒に使います。「the least」は、time, water, salt のような数えられない名詞と一緒に使います。
"This class has the fewest students in the school." では、"this class" が比べるもの、"has" が動詞、"the fewest students" が「生徒数がいちばん少ない」という意味です。英語では名詞の種類で形を選びますが、日本語ではどちらも「いちばん少ない」で言えることが多いです。"We have the least time today." では、"time" は1つずつ数えないので、"least" が正しいです。
