¿Cuál es la diferencia entre Up to date y Update ?Puedes dar oraciones como ejemplo.

"Up-to-date" is an adjective. For example, "this textbook is up-to-date. The information in it is new and useful."

"Update" is a verb or noun (depending on how you use it). If you want to compare this word with "up-to-date," you should use the adjective "updated."
The difference between "up-to-date" and "updated" is this:
- If you say that a textbook is "updated," it means that the textbook as an old version with old information in it. The updated version of the textbook is the newer (and better) version.
- If you say that a textbook is "up-to-date," it does not always mean that there is an older version somewhere. The textbook could have simply been printed yesterday and this is its first edition. It is up-to-date because it is new and has good information, but it is not updated because it does not have an old edition.

I hope this helps.
