1. Adj. numeral. Equivalent to exactly nine times another number. I.e.: a number which then he is repeated ( adds ) eight times. 2. Sust. men's. The number which fully contains nine times to another number. Ex.: fifty-four is the nonuplo six. It is incorrect to say that it is nine times more, or greater, because then you would need to add nine times its value. Six is not six times more - no-one; It is five times higher. Yes it is in six-to-one ratio. The word derives from the latin 'nonus', syncopated version of «novenus»: ninth. The suffix 'plo' means 'many times': multiplicity.
