While I'm sure there are other name threads out here, I wanted to start one that isn't merely about why someone chose the name they did... but more about what the name means to you and your character. I also didn't want to necro a thread.
I'll start first.
I wanted to create a name for my character that was distinctly Caldari in nature, while still being pronounceable to most people I'd be interacting with. So, it needed to be simple, yet flavored and inspired.
Choosing to make a first name that is reflected in the real world (for easy use by those who've just met me), I started searching Finnish sources. I wanted a name that was powerful in its delivery, with a hard knocking consonant, as if the first letter of it hits you like a punch. The real world meaning of the name "Katrina" as 'pure' didn't really come into play, but it does slightly fit. Pureblood Caldari, and all.
For the out of character aspects, I knew I wanted a name that was easily shortened, and did not shorten into a word that I'd be uncomfortable with. Since most name shortenings tend to range between three to five letters, depending on the name... I aimed for three. Katrina fit this secondary requirement well, as it shortened to "Kat", naturally... and I like cats. The decision was easy, and I stuck with it.
For the last name, I started looking at Caldari system names after realizing that the Caldari name their systems after megacorp leaders. So, actual names were reflected in the systems. Sobaseki was the initial example I learned of, and I knew I wanted her to come from the planet Onitseru... so it rather became a portmanteau of the two names. ONI-tseru and soba-SEKI. Oniseki.
As I've grown more involved with the RP community, I think the name Kat has become something of a meme even. It's come to represent any number of odd or silly cat like things. It can be thrown into various words, and tends to... at least for me... deliver a sort of endearing quality to whatever the topic is, even if it is the most mundane or even repulsive for some cases. For example, my habit of rolling around OOC window using emotes... has given rise to the term "rollkat".
For myself, I am very pleased with the choices I've made with regards to naming. Not only has Katrina become a recognizable name, one not easily forgotten or messed up, but Oniseki lends itself well to any number of uses, such as the founding of a corporation... "Oniseki Holdings".
So how about your character names? What meanings hide behind your names? What meaning went into it, and what meanings have blossomed through the metagame?
