Structure
What are the elements that make up this word's structure?
This is my hypothesis for our word's structure so far:
dis + com + fit
The prefix disagree or disappear as proof.
The prefix company or compromise.
Prefixes, which are bound, lend any of their lexical content, or "meaning," to the base they are attached to. They do not carry this meaning in and of themselves. The prefixes disaster and comprehend. For this reason, I don't provide my students with those lists of affixes and their "meanings."
Let's check Etymonline to see if my proposed base
The entry in Etymonline tells me this word has been with us since Middle English, around 1200. As with many words in this time period, we received the word from Anglo-French. The Norman Conquest occurred in 1066. The Normans were the "Norse men" who lived in the Northern part of France, around the areas of Brittany and Normandy. When they took over England after the Conquest, they brought their language and culture with them, which is why we have so many French and Latin terms introduced into our language during this time period.
In Old French, the word was desconfire, a combination of des- and confire. The Old French (OF) des was a form of the Latin dis. The word confire came from a combination of Latin com- and facere, "make or do."
The Latin verb facere has many forms in English, of which
dis + com + fit
Let's see if we can find other relatives that share the base facere.
