In "For Esmé - with Love and Squalor", Esme seems to use "squalor" without knowing what the word means. Assuming she mistakes it for another word, what would the other word be? Good answers provide contextually appropriate words, which are written or spoken similarly to "squalor" (maybe "splendor") or convince that "squalor" is what she really means. Links to articles or online resources are more than welcome.
