An impression is a strong feeling or reaction that someone has about something or someone.
You probably use the word "impressed" all the time without even realizing it. When your friend shows off their new skills at a cooking class, you might say "Wow, I'm impressed!" It means you're really proud of them and think they did an amazing job. You can also be impressed by something in general, like a beautiful sunset or a cool gadget – it's just something that leaves you with a good feeling. If someone asks you to review their new business, and you're blown away by its unique features, you could say "I'm really impressed with what I've seen so far."
