forever

The word "forever" is a compound formed in Middle English from the intensifying preposition "for" and the adverb "ever." The Old English ancestor of "ever," ǣfre, is of uncertain origin but may be related to a phrase meaning "ever in life." The logic of the combination is transparent: "for ever" literally means "for all time" or "throughout always." This literal sense evolved into the modern abstract meanings of an unending duration or an extremely long period. The spelling eventually merged into a single word, solidifying its status as a unified lexical item expressing permanence.

Structure: for + ever - for (Old English): A preposition meaning "throughout, during, because of." In this compound, it functions as an intensifier meaning "throughout." - ever (Old English): An adverb meaning "always, at any time." It derives from Old English ǣfre.
