You're right! There are plenty of misnomers or names that may not accurately describe the things they refer to. Here are some other examples:
"Pencil lead": The "lead" in pencils is not actually made of lead, but rather a mixture of graphite and clay.
"Funny bone": The "funny bone" is not a bone at all but rather the ulnar nerve, which, when hit, can cause a funny sensation in the arm.
"Hamburger": Despite its name, a hamburger is typically made from beef, not ham.
"Guinea pig": Guinea pigs are not pigs, nor are they from Guinea. They are small rodents native to the Andes region of South America.
"Starfruit": While the fruit does have a star-like shape when sliced, it is not related to stars in the sky.
"Chinese Checkers": This game is not Chinese in origin but was actually invented in Germany.
"Koala bear": Koalas are marsupials, not bears.
"Grapefruit": The fruit is not a cross between grapes and oranges, as the name might suggest. It's a completely different fruit.
"Indian ink": The ink is used in traditional East Asian brush painting and calligraphy, but it's not originally from India.
"Pineapple": Pineapples are not related to pine trees or apples. They are a tropical fruit in the bromeliad family.
These examples show how names can sometimes be misleading, and their origins or associations might not accurately reflect what they represent. Language and historical usage often play a role in how these misnomers come about and persist.
