Usage

What does bin- mean? Bin- is a combining form used like a prefix, and it means “two” or “two at a time.” While it appears in a variety of scientific terms, it’s also easily recognizable in everyday terms. Bin- comes from the Latin bīnī, meaning “two each” or “by twos.”Bin- is related to the combining form bi- and is used with some words or word elements beginning with vowels. These two forms have similar origins, and for that reason, the difference between the two is a small yet important nuance: bin- tends to mean “double,” while bi- often means “twice.” Want to know more?

Explanation

A bin is a box or other lidded container. You might store onions and potatoes in a vegetable bin in your kitchen. The noun bin is especially good for describing a specific kind of container, like a toy bin at a preschool or a compost bin on the counter. Bin is more commonly used in Britain than in the United States — a Londoner might say, "Oh, just throw that in the bin," while a New Yorker is more likely to say, "Throw it in the trash," or "Toss it in the garbage." The root word is the Old English binne, "basket."
