妙麗曾經替家養小精靈組織的團體英文名字是什麼？

The Society for the Promotion of Elfish Welfare (often abbreviated S.P.E.W. or SPEW)

is a fictional organization in the Harry Potter series by J. K. Rowling. It is formed by Hermione Granger who is horrified with the way house-elves are treated. The organization aims to promote better conditions and freedom for house-elves. Hermione originally thought of calling it Stop the Outrageous Abuse of Our Fellow Magical Creatures and Campaign for a Change in Their Legal Status but realized that this name was too long to fit onto a badge. It has become known by its acronym, which Ron Weasley pronounces as the word "spew", and once asks if she's changed the name to "the House-Elf Liberation Front".
