I love etymology*, the study of the source of words. Some of the words in our current lexicon come from some seriously weird places. Take the common greeting Hello, for example. Hello has one of the strangest sources I've come across, one that is seriously out of place with its current use.

Hello is a bastardization of a 14th century phrase Hie below. Hie is from Middle English and means to go quickly. Below in this context meant persons who were underneath the speaker. You see, Hie below was a warning yelled out by upper story tenants when they were about to dump their chamber pots out of windows or off of balconies. It was a very quick method of saying "Whoever is underneath me better get their ass moving fast or they're going to be wearing a shit coat".

Hie below, as is typical for common phrases, contracted over the years. The first commonly recognized contraction in print was in Shakespeare's A Midsummer Night's Dream when Nick Bottom's character was being publicly ridiculed and despoiled. The feces coated weaver turned erstwhile player uttered the famous line "The eye of man hath not heard, the ear of man hath not seen; such unkind act with nary a hielow". This use of the word is one of Shakespeare's infamous double entendres. Bottom is complaining of both the lack of courtesy in a warning as well as the rudeness of not being properly greeted.

Usage of the word gradually shifted. With advances in sanitation there wasn't so much tossing of shit out of windows any more so that connotation died away. The word survived though and finally morphed into the common greeting of Hello that we all use today.

* Not to be confused with 'entomology', the study of bugs. Although that's pretty cool too.

NOTE: This entry, much like the contents of those chamber pots, is full of crap. The actual etymology of hello is boring as hell so I just made all of this up. Sounded good though, didn't it?
