Cách sử dụng
The word 'least' is used to compare things and find the smallest one. For example, if you have three books and you want to find the one that is the smallest or has the least pages, then you would use the word 'least'. Another example is if you have a group of friends and you want to find out who is the least tall, or who is the shortest. You can also use 'least' to talk about something that is not very important, like "the least important task on my to-do list".
