一半
yī bàn
In real, traceable use. Part of the curated seed collection; community review is coming.
Half of something, as an amount: half the people, half the money. It works like a noun: 一半的学生 'half of the students', 我喝了一半 'I drank half of it'. Unlike 半, it takes no measure word. In speech 一 changes tone, so it sounds yíbàn.
Một nửa của cái gì đó: một nửa số người, một nửa số tiền. Dùng như danh từ: 一半的学生 (một nửa số học sinh), 我喝了一半 (tôi uống được một nửa). Khác với 半, nó không cần lượng từ. Khi nói, 一 đổi thanh, nghe thành yíbàn.
