Cognomination

You select a new name or title for yourself, and write it, confirming your new name. All written instances of your previous name which referred to you change permanently and untraceably to reflect your new name, and anyone speaking to or about you may only use your new name. Anyone who attempts to speak your old name when referring to you finds themselves magically unable to pronounce it, and takes 1 point of psychic damage.
If you cast this as a ritual spell, the target may be one willing creature in touch range instead of 'self'. They select their own name or title.
