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?
