The condition of being unwell or having an illness is sickness. Your sickness during the month of November might mean you miss a lot of school.

A well-known, Christian version of wedding vows includes a promise to "have and to sickness and in health." This means the couple agrees to stay together and support each other whether they're healthy or ill. Some sickness is a chronic or permanent kind of malady, while others are more specific, like morning sickness during pregnancy or a brief flash of sickness when your plane hits a patch of turbulence.
