Late Middle English: from French chronique, via Latin from Greek khronikos 'of time', from khronos 'time'.

  • Words beginning chron- have something to do with time: the root being Greek khronos ‘time’. A chronic illness is one that persists for a long time. In informal British English the word can also mean ‘of very poor quality’, as in ‘the film was chronic’, a sense developing from the idea of unending tedium. See also anachronism, crony
