Etymology

Origin of condition

First recorded in 1275–1325; Middle English condicioun, from Old French, from Latin condiciōn-, stem of condiciō “agreement,” equivalent to con- con- + dic-, stem of dīcere “to say” + -iō -ion

Explanation

A medical problem or illness can be referred to as a condition. Your skin condition isn't contagious, but it still looks bad — scabby and scaly. You won't even need makeup to dress as a zombie for Halloween. A condition is also a requirement or prerequisite for something. As a condition of your acceptance to college, you may have to maintain certain grades and do well on a standardized test. Condition can refer as well to the state or quality of something. The condition of your apartment building might be so appalling that your mail carrier has stopped delivering your mail.
