chronicity

The word chronicity is a modern English formation built upon the classical root for time. Its foundation is the Greek khronos, meaning "time," which passed into Latin as chronus and entered English via learned borrowings. The suffix -ic was added to create the adjective "chronic," originally meaning "of time" or "long-lasting," which became specifically medicalized to describe persistent diseases. Finally, the abstract noun-forming suffix -ity was appended to "chronic," generating "chronicity" to denote the state or condition of being long-lasting and persistent. Thus, the word's logic moves from the ancient concept of time, through the characterization of duration, to the modern abstract quality of persistence, particularly in a medical context.
