Which spelling details matter here?
English reads large numbers in three-digit groups. 1,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 reaches the novemdecillion group, so the group one is followed by the scale name novemdecillion. Scale names stay singular inside exact number names. English writes one novemdecillion without adding a plural s to the scale name. When a three-digit group is 000, English skips that group in the word form. This keeps one novemdecillion shorter and easier to read.
How should these words be spaced?
American standalone spelling uses spaces between scale groups and hyphens in compound tens.
