Etymology

The word "alone" originated in Middle English as a contraction of all one, emphasizing the idea of being "entirely by oneself." Over time, the phrase merged into a single word, retaining its core meaning of solitude or exclusivity. The logic is straightforward: "all" intensifies "one," reinforcing the notion of singularity.
