Syllogism

Syllogism is a noun that refers to a form of logical argument featuring two propositions and a conclusion. 

Our word of the day combines the Greek word sullogismos (soo low GISS mos) with another Greek word logos (LOW goes) which means ‘reasoning.’ Here’s an example of syllogism in use:

I was perplexed by my philosophy teacher’s behavior, I tried to use a syllogism to understand his logic. It didn’t get me anywhere. I found two propositions, but the only conclusion I reached was that Mr. Dolenz is weird.
