Definition 1: In a manner characterized by a combination of desire and expectation.

Usage 1: Constructions like "Hopefully, it won't rain" are often condemned¹ because such statements contain nothing capable of hope for the adverb to modify. But it is odd that similar constructions using "frankly," "sadly" and "mercifully" are likely to pass without comment?hopefully" has for some reason been singled out for disapprobation. Although there is now general acceptance that such "sentence adverbs" may be used to indicate the speaker's frame of mind, you may wish to avoid them if your speech or writing is going to be critically scrutinized². The noun and verb "hope" are parents to the adjective "hopeful" and its opposite "hopeless," and their associated nouns "hopefulness" and "hopelessness."

Suggested usage: Test the knee-jerk pedants³ by using "hopefully" appropriately: "Hopefully, I'll be in the casino tonight." (You wouldn't go if you weren't hopeful.) But beware that a sentence adverb can be misinterpreted if people are the subject of your sentence: "They're to be married, hopefully, in the spring." (Do you hope for a spring wedding, or is their betrothal⁴ to be founded on nothing more than hope?)

Etymology⁵【语源】: "Hope" seems to have simply sprung into existence as Old English "hopa, hopian." The suffix⁶ "-ful" comes from "full," a Germanic word that has undergone the usual transformation⁷ of [p] to [f] as it evolved from the Proto-Indo-European *pel. The PIE word spawned⁸ Greek polus, "much," and plethos, "many." From these we derive⁹ the prefix¹⁰ "poly-" which indicates an abundance, and the noun "plethora," a super-abundance. The same PIE root underlies¹¹ Latin plenus, "full," from which we have English "plenitude" and "plenty."
