The state of being normal or the absence of anything strange, unusual, or problematic.
From 'normal' (from Latin 'normalis' meaning perpendicular or according to rule) plus the abstract noun suffix '-cy'; popularized by U.S. President Warren G. Harding in 1920.
Harding's campaign promise of a 'return to normalcy' after World War I was so catchy it made the word itself famous—even though language experts initially thought 'normality' was the correct form.
