"rhetorical" power names: the sound of a character's name or perhaps its origin or what it might allude to--all of these convey meanings that add to our understanding of the character. Mrs. Reed’s name suggests her strictness, a “reed” being a tool that punishes children by whipping them. Mr. Brocklehurst’s same, with the “k” sounds in the middle, also sounds harsh, but it also sounds pompous, which in fact he is. Helen Burns is a passionate girl; in some ways she “burns” with life, and of course she dies from a fever as well. Blanche might sound elegant, but the name half-rhymes with “bland,” which she certainly is, for she lacks the strong moral compass that guides Jane. As for Jane, yes, her name is plain, but “Eyre,” although it too sounds plain in that it consists of a simple syllable, also conveys an ethereal quality in that it is a homonym with “air.” Insofar that “eyre” is also a system of justice in Medieval England, perhaps her name brings with it suggestions of the fairness and the sense of right she seeks and represents. Bertha originates from a German word that means “bright,” which is ironic in terms of the way Rochester has locked her up so that she now lives in the dark.
