The action or habit of estimating something as worthless, but used chiefly as a curiosity word (bet you can't guess why ;). Floccinaucinihilipilification takes its meaning from a bunch of Latin words meaning 'worthless'. It is said that a Latin student was trying to prove a point, and he strung them all together to make the word floccinaucinihilipilification.
This whole thing is floccinaucinihilipilification.
A literary device that involves each word of a sentence or phrase (generally three words or more) beginning with the same letter. Alliteration can be used to draw attention to an important point or phrase, for emphasis, or just because it sounds better.
"What was worse was when what woke Willa went west with William" is a prime example of alliteration.
