Etymology

Origin of installment1

First recorded in 1770–75; in- 2 + obsolete (e)stallment, equivalent to estall “to arrange payment on an installment plan” (perhaps from Anglo-French ) + -ment

Origin of installment2

First recorded in 1580–90; install + -ment

Explanation

An installment is a part or section of something, like the monthly installment you pay on your credit card debt or the latest installment of your favorite TV show. "Partial payment" is the oldest meaning of this word, and it's still a common way to use it: "She sold me the bike and I'm paying her in installments." It's also used for anything split into sections or episodes. Your favorite serialized comic comes out in installments every three months, but you only have to wait a day for the next installment of that afternoon soap opera!
