I never had any nicknames at all -- not in the sense of a thing somebody would call me in place of my name; I consider endearments to be a separate category. My given name doesn't even lend itself to a diminutive form, and my family name is just 100% unmanageable. There were kids in school (as well as one P.E. coach) who mangled it as a form of mockery; that was pretty much indistinguishable from the normal state of affairs, and didn't bother me much.

I don't know whether the unusual nature of my legal moniker is the reason that names have always been a Thing for me in stories, to the point where I have to ration out my allotment of name tropiness (and then it sneaks into stories that weren't supposed to have any of that sort of thing anyway). Not just true names as a means of enchantment: names with obvious literal meaning (thank you, Elfquest); names with hidden symbolic meaning; characters changing their names because of major life events; characters having multiple names depending on who's speaking to them or where they are. If it's a name-related trope, I probably love it.

You could probably enchant me with "Marie Brennan." Sometimes things attach firmly enough that you can have more than one true name.
