The story of the word

Walther Flemming coined it in 1882 after watching stained salamander cells and seeing the nuclear material behave like threads pulled apart. He had already named that stainable material chromatin, from χρῶμα, colour. Meiosis, the halving division, was named in 1905 from μείωσις, a lessening. μίτος is a weaver's word, the thread the shuttle carries across the warp.
