Don't get me wrong, new words are fun (eg: susurrus: A whispering or rustling sound; a murmur) but etymology is my drug.
For example, "nick-name" came from "eke-name", (literally an 'also-name') probably as the result of someone young and impressionable person hearing "an eke-name" and interpreting it as "a nick-name".
Words' meanings can also change over time - even completely flip in meaning.
For example, in the King James Bible: "It repented the Lord that he had made man on the earth." This is clearly a different meaning of repent to our own; repent here means "made to regret".
Even greater changes of meaning have occurred, with much more common words: "like", in Shakespeares' day could mean both "pleases" and "like":
HOST: The music likes you not? (Don't you like the music?)
JULIA: You mistake; the musician likes me not. (You misunderstand; I don't like the musician.)
(
The Two Gentlemen of Verona)
Here's a funnier one: "Silly" came from the West Germanic gesaelig, meaning "happy. It then moved onto "blessed", as in "the silly Virgin Mary" and continued on to "pious", but the very common link with Mary pushed its meaning on to "innocent" in 1200, to "harmless", to "pitiable" in 1280, to "weak" by 1300 and finally to "foolish" in 1576.
