Curious Chloride & Titanic Chloride

Compounds of metals sometimes have curiously strange common names. Curium trichloride (CmCl₃) may be called curous chloride or curious chloride. Similarly, titanium tetrachloride may be called titanic chloride. In the titanium industry, TiCl₄ is sometimes called 'tickle'. Certain nickel compounds are called 'nickelous' and curium oxides are called 'curates'. You can get compounds such as nickelous curate. Sounds like it could be a person's name, doesn't it?
