It's impossible to know every single word in the English language. But there are words for things we use almost every day and have no clue what they are.
These are some things you had no idea there was a name for.

No, it's not a snack. Nibbling is a gender-neutral term for either a niece or nephew.
"I'm going to visit my nibblings today."

"I'm buying gifts for my nibbling!"
That little blob of toothpaste has a name, and that name is nurdle.
The favorite smell of many people, petrichor refers to the scent of nature after a rainfall. While some people think this scent is fake, it's a real thing and it smells heavenly.
