a·loneness n.

Synonyms: alone, lonely, lonesome, solitary
These adjectives describe lack of companionship. Alone emphasizes being apart from others but does not necessarily imply unhappiness: "I am never less alone, than when I am alone" James Howell.
Lonely often connotes painful awareness of being alone: "'No doubt they are dead,' she thought, and felt . . . sadder and . . . lonelier for the thought" Ouida.
Lonesome emphasizes a plaintive desire for companionship: "You must keep up your spirits, mother, and not be lonesome because I'm not at home" Charles Dickens.
Solitary often stresses physical isolation that is self-imposed: I thoroughly enjoyed my solitary dinner.
