> fair lengths of natural language interspersed with [greek with a smattering of hebrew, hiragana, etc.] Also some made up stuff also. For example in financial maths, the the derivative of an option's price with respect to volatility is called "vega". Why? Well because all the other option derivatives are named using Greek letters (delta, gamma, rho etc) and "vega" sounds sort of Greek even though it's just made up.[1] [1] I haven't heard a convincing etymology for vega in financial maths but it's generally written using the letter "nu" which just looks like a "v" https://en.wikipedia.org/wiki/Greeks_(finance)#Vega https://en.wikipedia.org/wiki/Greeks_(finance)#Vega
