Re: Missing term

Yes, it took about the same time for me to learn that taunt and taut
were not homophones, and I still sometimes pronounce accelerate,
axe-sill-er-ate.

Regarding freezing, I think one should differentiate between the
increase in viscosity when glasses are cooled and other liquids
crystallize.  Glasses are still liquids when called solids because they
still flow and there is not a demarcation in their properties.  i.e.
their viscosity smoothly increases on cooling and there is no "heat" of
fusion.  "Heat" must be "extracted", of course, for this viscosity
increase to occur, but there is no "discontinuity".  There are other
differences, e.g. how they fracture.
