# What is it called when you multiply something eight times? [closed]

I know that the prefix for eight is "oct". Does this mean that the word I am looking for starts with"oct"? I have done quite a bit of research. Almost every time the first website listed is this one. I really hope that this will be the end of my research! Thank you!

• Please give us an example. It’s not clear whether you mean n*8, n^8, or n*(m^8), etc

Octuple:

to make eight times as much or as many. (M-W)

Or

Eightfold:

(Mathematics) by or up to eight times as much.

(Collins English Dictionary)

• A verb 'to octuple' is certainly morphologically well_formed, but I think it is rare, and for good reasons. I think that 'sextuple' is at the limit of widely used multiples. 'Septuple' begins to sound a bit odd, 'octuple' somehow less so, but nine times? Nonuple? Surely not. As for 'ninefold' (by analogy with 'eightfold'), you cannot 'ninefold' something. You might increase it nineford. Commented Apr 30, 2019 at 22:04
