What does septuple mean?
Septuple means seven times as great as something else, and it can describe a quantity, act as a verb meaning to multiply or increase something sevenfold, or appear rarely as a noun for a sevenfold amount or increase. Its use often suggests a dramatic numerical jump, although the word itself does not imply whether that change is beneficial. For example, a septuple increase might describe a surge in revenue, traffic, or demand just as readily as a surge in administrative workload. The verb can be transitive, as in “the merger septupled the company’s output,” or intransitive, as in “applications septupled over the following year.” In ordinary prose, sevenfold is often more natural, while “multiply by seven” may be clearer when explaining a calculation. Nevertheless, septuple is useful as a compact, formal expression for an exact sevenfold relationship.
Equal to seven times the original quantity or amount.
"The company achieved a septuple increase in annual revenue."
The adjective normally precedes a measured noun or an expression describing a quantity.
To make or become seven times as great as before.
"The redesign septupled the number of visitors to the site."
The word can be transitive, taking the thing that is increased, or intransitive, describing the increase itself.
A quantity equal to seven times another quantity, or a sevenfold increase.

This noun use is relatively uncommon and is chiefly found in formal or technical contexts.
The plural is used when referring to separate sevenfold quantities or increases.

Septuple comes from the same Latin number root as seven and September: all ultimately point to the number 7.

Where does septuple come from?
Septuple comes from Latin septuplus, meaning “sevenfold,” which was formed from septem, “seven,” together with a suffix expressing multiples. English borrowed the form with the development of modern scientific and quantitative vocabulary. The same Latin root produced related forms such as septet, septenary, and septillion, as well as the English word seven.
