Sentence:  "I like names that end with an a, don't you? Or other vowels? Most often it seems to be an a. But wait: <WSD>Margo</WSD>'s name ends with an o, for mercy's sake! Barnaby's mother. Or it used to be o. Then she met Barnaby's father and added a t." / Sophia looked at me. I told her, "Mom thought Margot with a t was higher class." 
Meaning of the word marked with <WSD> tags:  (from=French), a phonetic rendering of (en) Margot.
