The story of the word

The solid in the name is a gallstone. Chevreul isolated a waxy substance from them and called it cholesterine, bile-solid, and when chemists found a family of compounds built on the same skeleton in the 1930s they cut the name down to sterol and then steroid. Stereo, meaning solid sound in three dimensions, is the same first element.
