More about algorithm

More about zaffer

For the origin of zaffer, “a cobalt oxide–silica mixture used to produce a blue color,” let’s travel down a linguistic rabbit hole. Zaffer, from French safre or Italian zaffera, may come from Arabic ’aṣf, “yellow,” which resembles but is not related to saffron and sulfur. Alternatively, zaffer may come from Latin ī, “sapphire,” via Ancient Greek á𾱰Dz, “lapis lazuli,” from a Semitic source akin to Hebrew ī, “sapphire.” One intriguing proposal is that ī and its close Semitic relatives come from Sanskrit śԾܰⲹ, “dear to Saturn,” equivalent to ŚԾ, the planet Saturn, plus á-, “dear.” Zaffer was first recorded in English circa 1660.

EXAMPLE OF ZAFFER USED IN A SENTENCE

The glass blower used zaffer to make the vase a beautiful hue of azure.

More about barococo

Barococo, “excessively ornate in style,” is a portmanteau, or blend, of baroque and rococo, two words of complicated origins. Baroque is a borrowing from French and comes from older Portuguese barroco or Spanish barrueco, “irregularly shaped pearl,” and from here, numerous linguists have weighed in with their ideas. Perhaps there is a link to Spanish berruca, “wart” (from Latin ū). Rococo is also borrowed from French and derives from Medieval Latin rocca, “rock,” which may come from a Celtic source or, alternatively, Latin ūŧ, “cliff.” Barococo was first recorded in English in the mid-1920s.
