Loan Sharks are Not Named After the Sea Creatures
Even if you have no understanding what a loan shark is, you can probably tell that they are potentially harmful. And even after you do, it still sounds risky. A loan shark is, to put it simply, someone who will provide you a loan with very unfavorable terms. If you don't pay it back on time, there can be risky fines or excessive interest rates. This usually denotes a criminal act, such as maybe breaking your legs. You should stay away from loan sharks.
The connection to sharks is apparent. A loan shark is similar to a financial predator, just like a shark is a predator in the sea. Strangely enough, a loan shark does not receive its moniker from this. They are unrelated to aquatic life, and the shark is merely a term that they share by coincidence with another animal.
In the past, sea dogs were the actual name for sharks. There are still several small shark species that go by the name of "dog fish." But the term "loan shark" comes from the word "shark," which has long been used to describe a dishonest or dishonest person. That term predates marine sharks and could have Germanic or Dutch roots, such as the word "schorck," which means rascal.
