concentrated

Concentrated means that something has been made more powerful or intense by taking away some of its less important parts.

When we say that a flavor is concentrated, it means that all the good taste is packed into a smaller amount. If you like coffee but don't want to drink too much of it, you might buy concentrated coffee that's been squeezed down so there's more flavor in every little packet. This way, you can make as strong or weak a cup as you like.

If someone says they've read a concentrated version of a book, they mean that it's all the main bits put together without extra words or details. It might be useful if you only have time to read a short summary. Sometimes people take notes in class and then write them down in a more condensed form later, so their ideas are really focused.
