Question: What is another name for the fairy queen referred to as Queen Mab in Romeo and Juliet? 
Sentence (from "Queen Mab"): She may be a figure borrowed from folklore, and though she is often associated with the Irish Medb in popular culture, and has been suggested by historian Thomas Keightley to be from "Habundia", a more likely origin for her name would be from Mabel and the Middle English derivative "Mabily" (as used by Chaucer) all from the Latin "amabilis" ("lovable").
Relevant evidence: No
