What does unessential mean?
Unessential means that something is not necessary or indispensable for a particular purpose. It is an adjective, and it appears most often in formal English, especially in British usage. The term can describe a detail that adds little to an argument, a stage in a process that may be omitted, or a feature that is not required for a product to function. Although “nonessential” is often the more familiar choice, “unessential” is useful when a writer wants a slightly more formal register. Its meaning is broader than “unnecessary”: an element can be unnecessary because it is redundant or excessive, whereas it is unessential when it is simply not required. The word therefore makes clear that absence from a design or explanation does not imply that the missing part is worthless. It is a useful word for distinguishing what a thing truly requires from what is merely optional.

Where does unessential come from?
Unessential was formed in English during the seventeenth century by combining the prefix un-, meaning “not,” with essential. Essential comes through French from Latin essentialis, which was derived from essentia, a term associated with the Latin verb esse, “to be.” Related words such as essence and entity also trace back to this Latin family.
