Usage

What does probably mean? Probably means most likely or in all likelihood. Probably is the adverb form of the adjective probable, meaning “very likely to occur or be true.” Probably is used when you think something will happen or turn out to be true, but you’re not certain enough to say it definitely will. Example: My flight will probably arrive within the next few hours, but I can’t guarantee it.

Etymology

Origin of probably

First recorded in 1525–35; probable + -ly


Explanation

If something probably will happen, it's likely. If it probably won't happen, don't get your hopes up. This is a word for things that are likely to happen or just believable. If your dinner is gone and your dog looks guilty, the dog probably jumped on the table to eat it. If someone moved all the furniture around while you were sleeping, you probably would have noticed.
