Most of natural language processing (NLP) is built off of unigrams—that is, single words or word-like things (like an emoticon or a !?!?). Models sometimes give you bigrams and trigrams. When people talk about these as a group, they refer to n-grams. But why use “6-gram” when you can say “sexagram”? I think you’d only say 13-gram if you were “absurdly absolutely irrationally fearful frightened and afraid of other lovely words like triskaidekaphobia” (that’s a triskaidecagram for you, you can spell it with a k or go for the resonance of a middle-c).
Note that you can swap out “-gram” for your favorite root. Why call it an 18-wheeler when you can call it a octakaidecacycle?
One of the most peculiar numeral words in English is “zenzizenzizenzic”, which means “the eighth power of a number”, as in “The zenzizenzizenzic of 2 is 256”. It was used only once in English, in Robert Recorde’s The Whetstone of Wit (1557). It is derived from an equally-obsolete “zenzic”, which referred to the square of a number. It is the only English word with six Zs, and is thus, if I may be allowed to coin a term, hexazetic.
