Here are some examples:
* "I thoroughly enjoyed the movie." (This means the speaker liked the movie very much, with no reservations.)
* "The police thoroughly investigated the crime scene." (This means they looked at everything, leaving no stone unturned.)
* "The cake was thoroughly baked." (This means it was baked all the way through, not just on the outside.)
"Thoroughly" is often used to emphasize the completeness or intensity of an action or experience. It's a good word to use when you want to convey that something was done very well or that something was experienced in a very intense way.
