When we talk about something that is "extremely good," we often use the phrase "very good" or "excellent" in English. These words can be used to describe anything from a performance, a meal, or even a piece of art. For instance, if someone has done an outstanding job at work, you might say, "That was an excellent job!"

The word "excellent" itself is quite strong and implies a high level of quality or achievement. It's commonly used in both formal and informal settings. On the other hand, "very good" is a bit more casual and versatile, making it suitable for everyday conversations.

In certain contexts, you might also hear phrases like "top-notch" or "first-rate" to convey a similar meaning. These terms suggest that something is of the highest standard or quality.

Remember, while these expressions are widely understood, the tone and context in which they are used can greatly influence their impact. Using them appropriately can help enhance communication and express admiration effectively.
