This is a great blog – etymology allows you to follow thousands of years of unguided, random history and find it all preserved in the words you’ve always been saying.
Before chemists had a detailed understanding of molecular structure, newly discovered chemicals were named on the whims of the discoverers. By the end of the 19th century the number of organic molecules known to science had started to increase dramatically, and the list of unconnected names that had to be remembered was getting longer and longer. It became apparent that this mess had to be sorted out, and the process of developing the systematic naming conventions that we have today began. However, despite being less descriptive, many of the old names are retained in the language today and referred to as trivial or common names.
