Cách sử dụng
'Free' means when something is given to someone without having to pay any money for it. For example, when someone offers you a free meal, it means you don't have to pay for it. You can also use 'free' when talking about something that is not restricted or limited, such as free time or free speech. It's important to remember that 'free' can sometimes have conditions attached, so always make sure to read the fine print before accepting something for free.
