Structure
What are the elements that make up this word's structure?
My initial prompt for this investigation had me wondering about this words base. My initial hypothesis is:
de + bauch + ery
Let me tell you why.
The suffix <-ery> appears on numerous nouns. We have bakery, scenery, and misery. The Etymonline entryfor this suffix tells me that it has a history of <-erie> in Middle English or <-arius> in Latin, along with a relationship to suffix <-ary>. You can hunt for some suffixes on Etymonline by inserting a dash before your suspected element. I now know that if my word debauchery has an earlier roots with those two historical endings, there's a good chance my word shares that history.
I also am thinking of the prefix entry. This is why I don't pay much mind to those lists of affixes you see on the internet and their "definitions." You have to look at what sense the affix is lending to the base in the particular word you are studying. In many words, the prefix debauchery.
However, all of this is conjecture until we find evidence in an etymological dictionary, so let's go to the entry for debauchery itself.
Right away at the entry we see debauch + ery. Although I've not heard of a word debauch, we must follow that entry to see if the
In the entry for debauch, we see that the word came to us from French. My initial thinking about "vaguely French" has been confirmed. The word is from an Old French verb desbaucher, "lead astray." The trail grows cold there.
However, I know that entry in Wiktionary instead. I will often head over to Wiktionary when the roots are buried in another language besides English.
Here, we find that it's possible that this is de + bauch, since the French form could be analyzed as des + bauch. The bauch may have meant "beam of wood." It may have meant to trim this beam of wood and then was extended to mean trim you of any virtue in the more modern sense of debauchery.
For myself, I think it's safe to leave the word sum as debauch + ery. Since bauch doesn't generate many other English words, we could treat the whole debauch as the base.
