means To kindle is to start a fire or get a flame going, and by extension to spark a feeling, interest, or passion into life.

from From Old Norse 'kynda,' to set fire to, which settled into Middle English as 'kindelen.' It likely tangled along the way with another Middle English 'kindel,' meaning to give birth (think of an animal bringing forth young), so the word carries a faint double warmth: igniting a flame and bringing something newly alive. The brand name borrows that older spark — a device meant to kindle a love of reading.
