18.04.26: Describing objects [15]; gemstones (iii); Where are they hiding?

[1] adamās, -antis [3/m]: diamond

If you’re adamant about something, you’re firm, unshakeable in your opinion. The origin of that word is partly hidden in diamonds! Adamās, adamantis – apart from translating as ‘diamond’ – can also refer to the hardest forms of steel or iron, in fact anything that is inflexible and lasting.

adamantīnus, -a, -um: hard as steel

[2] carbunculus, -ī [2/m]: ruby

The word can refer to any reddish-coloured stone e.g. ruby or garnet, or carbuncle. However, ‘carbuncle’ is far more commonly used in English to any kind of cluster of boils forming a connected area of infection. You have a choice: search ‘carbuncle’ in Google images, or simply take my word for it!

It is also a term for an ugly building i.e. an ‘eyesore’ and famously used by the Prince of Wales (now Charles III) to describe the 1984 extension plan for the National Gallery as “a monstrous carbuncle on the face of a much-loved and elegant friend"

[3] ēlectrum, -ī [2/n]: amber

> electric > electrical / electricity

How did that happen?

https://en.wikipedia.org/wiki/Electricity

“Ancient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. … Electricity would remain little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert wrote De Magnete, in which he made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. He coined the Neo-Latin word electricus ("of amber" or "like amber", from ἤλεκτρον, elektron, the Greek word for "amber") to refer to the property of attracting small objects after being rubbed."

Now you know 😊

ēlectricitās, -tātis [3/f]: (Neo-Latin) electricity

ēlectricus, -a, -um: (Neo-Latin) electric

[4] The popularity of first names can vary over time, some names becoming far less common than they were, say, a century ago. However, some girls’ names have their origins in Latin or Greek:

Beryl (La: bēryllus, -ī; Gk. βήρυλλος / bḗrullos)

Gemma (La: gemma, -ae)

Margaret (La: margarīta, -ae; Gk. μαργαρίτης / margarítēs)
