Favourite word and why

[Vampyr]

Quintessence.

Cool sounding word, cool meaning, and in the coolest Shakespeare monologue ever.

"What a piece of work is a man! How noble in reason! How infinite in faculty! In form, in moving, how express and admirable! In action how like an angel! In apprehension how like a god! The beauty of the world! The paragon of animals! And yet, to me, what is this quintessence of dust? Man delights not me; no, nor woman neither, though, by your smiling, you seem to say so." - Hamlet
