Okay everyone, it's time to engage your Se! What words do you find particularly striking or interesting in the way they sound? It can be good, bad, whatever.
I've always found the word "sepsis" (blood infection, for those of you who don't know) to be quite stinging. All of those s's blended together with the p in the middle give it an eerie, deathly sound, which goes perfectly with it's meaning.
