Etymology

Origin of solitary

1300–50; Middle English < Latin sōlitārius alone, by itself, solitary, equivalent to sōlit ( ās ) solitude ( sōl ( us ) sole ¹ + -itās -ity ) + -ārius -ary

Explanation

If you're a lone wolf, a one-man band, a rugged individualist, or an island unto yourself, you prefer to be solitary — in other words, alone or single. The term can be used to describe a person, a place, or a thing. Solitary comes to us from the Latin solus, which means alone. Note its similarity to words like solo and, for all you card players out there, solitaire. You can take a solitary walk, during which you don't utter a solitary word, but pause to admire a solitary green shoot peeping through the snow. Solitary is also common in the prison world: Inmates on Alcatraz who were deemed too dangerous to mingle with their fellows were put in solitary confinement cells.
