Be careful with this one if you want to please the pedants.
Most of us use the word to mean we hope it will be OK. For example “Hopefully I’ll catch the last bus”. The word has been in use this way for a very long time. Some people still insist it means full of hope, so they would interpret the example to mean I was planning to board the bus with a positive attitude. Perhaps I think this time there will be fewer drunken idiots. Most of us would mean we don’t want the alternative of a long walk.
So the message is simple. If you want to be sure you aren’t making the purists tut, hopefully is a word to avoid.
