(Of an illness) persisting for a long time or constantly recurring.

Chronic is the opposite of 'acute' (which is sudden and short-lived). It implies a condition that must be managed over years.

The story behind the word. 'Chronic' comes from the Greek 'khronos', meaning 'time.' This is the same root that gives us 'chronology' and 'chronometer.' A chronic illness is quite literally a 'time illness'—one that stays with you as time passes.

  • persistent: Continuing to exist over a prolonged period, but less clinical than chronic.
  • inveterate: Long-established and unlikely to change (usually used for habits, not diseases).
  • acute: Present or experienced to a severe or intense degree, but usually short-lived.
  • temporary: Lasting for only a limited period of time.
