The word "hopefully" is an adverb used to express a desire or expectation that something will happen in a particular way. When we say something is "hopefully" going to happen, we are expressing optimism about the outcome. It conveys a sense of wishing or longing for a positive result.
The word "hopefully" is derived from "hope," which comes from the Old English "hopa," meaning "expectation." The suffix “-fully” is used to form adverbs indicating manner, thus "hopefully" essentially means "in a manner full of hope."
