I didn't take that the author was trying to make a point, rather pondering about when a word becomes worthy of inclusion in the dictionary. "Boiling water" is a word that hasn't (yet) been deemed worthy. On the other hand, "hot water" is a word that is included in the dictionary, just as "still water", "warm water", etc. are. Somewhere between those included and "boiling water" is line where a word becomes worthy of inclusion. But where, exactly, is that line?
