"Don't use words too big for the subject. Don't say "infinitely" when you mean "very"; otherwise you'll have no word left when you want to talk about something really infinite"
About this Quote
The line works because it treats language like a finite resource, not a bottomless toy chest. Hyperbole becomes a kind of deficit spending: you get a quick hit of emphasis now, but you are left linguistically bankrupt when you need to describe the absolute. Lewis, a Christian apologist and a medievalist, is also protecting a word with theological and philosophical stakes. "Infinite" is not merely "a lot"; it gestures toward the unbounded, the divine, the conceptual edge where human measurement fails. To use it as a synonym for "very" is to flatten the vertical dimension of experience into consumer-grade enthusiasm.
There's also a quiet jab at pretension. "Words too big for the subject" indicts the insecurity that reaches for grand diction to dress up small thoughts. Lewis is arguing for proportion: match your language to your meaning, so that when you finally confront the truly immense, your vocabulary still has the muscle to lift it.
