I'm interested in words, from any language, whose etymological origin 'exposes' superstitious or scientifically obsolete beliefs.
For example, the English disaster comes from Latin dis- + astro, meaning literally bad star or ill-starred. This 'exposes' Roman astrological beliefs. Similarly, the English lunatic comes from the Latin luna, meaning moon.
Another example is the English malaria from Italian mala + aria, meaning bad air.
Are there other examples of words like this, where evidence of ancient beliefs is embedded in everyday words?
