The Etymology of Polyglot

    Figure 1:   A tongue that I quickly sketched, and then edited in photoshop. The Ancient-Greek 1st-and-2nd-declension adjective: πολύς, πολλή, πολύ , or, when transliterated: ‘polús, pollḗ, polú,’ means: ‘many,’ .  The Ancient-Greek 1 st -declension feminine noun: ἡ γλῶσσα, τῆϛ γλώσσης, or, when transliterated: ‘hē glȭssa, tē̃s glṓssēs’ means: ‘the tongue’ .  In the Attic dialect, the spelling of: ‘hē glȭssa,’ is: ἡ γλῶττα, τῆϛ γλώττης , or, when transliterated: ‘hē glȭtta, tē̃s glṓttēs’ . We derive our English noun: ‘polyglot,’ , which is a speaker of many languages, from our combining of the Ancient-Greek adjective: ‘polús,’ which means: ‘many’ , with the Ancient-Greek noun: ‘glȭtta’ , which means: ‘tongue’ .

The Naming of Sets in Set Theory Figure 1:   I drew this set-naming italic character in SVG.  You may view the code of this image at my Codepen Account . Figure 2: What the SVG image looks like when exported as a PNG. [1] In Set Theory - which underpins so much of computing mathematics - we conventionally name sets with capital italic letters. In computer science, a name such as: A , would be termed an: ‘identifier’ . In the below example, we shall use the capital italic character: R so as to name the members of the set of Radix-ten [2] integers. Figure 3: “ A SQUARE-ROOT SIGN   This sign is from radix (Latin for root) and was first used by Leonardo da Pisa in 1220.  Today’s √ sign, which may be a distortion of the letter “r”, is sixteenth-century German.” [3] An Example ...
