Cách sử dụng
The word 'guesswork' is used when you make a guess or an estimate about something without having any solid information to back it up. It is often used when you are unsure about the answer or the outcome of a situation. For example, if you are asked to guess how many people attended a concert, and you have no idea, you might say "I'm just using guesswork, but I think maybe around 500 people."
