That's fantastic

You can use it as a standalone reaction. If a friend says they got a promotion, you just say, That's fantastic! You can also use it to describe things. For example, The food at this party is fantastic. It works for big life events and small daily wins. It shows you are paying attention and you care.

Use it whenever you want to boost someone's mood. It is perfect for celebrating achievements. Use it at a restaurant when the waiter asks how your meal is. Use it in a meeting when a colleague shares a great idea. It’s a great way to be the 'cheerleader' in a conversation. Even a simple text message with this phrase can make someone's day.

Avoid using it for sad or serious news. If someone says their car broke down, don't say it! That would be very awkward. Also, be careful with your tone. If you say it with a flat voice, people might think you are being sarcastic. Sarcasm is when you say the opposite of what you mean. Don't use it if you are actually annoyed.

English speakers, especially in the US and UK, love using 'strong' adjectives. We often skip 'good' and go straight to fantastic or amazing. It reflects a culture of outward positivity. In some cultures, people are more reserved. In English, being 'extra' with your praise is usually seen as being friendly and supportive. It’s a social 'glue' that builds fast connections.

You will hear many similar words. That's awesome is very common in the US. That's brilliant is a favorite in the UK. If you want to sound even more excited, try That's absolutely fantastic! If you want to be a bit more casual, you can just say Fantastic! on its own. It’s like a verbal high-five.
