Etymology
Origin of lonely
Explanation
There are a few definitions of lonely but they all share the same qualities: solitude, the absence of human company, and not a lot of exciting stuff going on. If being alone makes you sad, that’s one definition of lonely: the depressing feeling you get when no one else is around. Being alone doesn’t have to be a bummer, and sometimes lonely simply means preferring to be by yourself, like the lonely poet who takes long walks in the woods. Mars is a lonely planet because no life can survive there, and on a cross country trip you’ll drive down many long and lonely roads.
