Yeah, that sounds good. We generally try not to use abbreviations in our function names, so they're as human-readable as possible, so I'd go with getNumericalTerm or getNumberTerm.

We need two functions -- conversion from "1 time" and "2 times" to "once" and "twice" and conversion from "2x", "3x", and "4x", to "double", "triple", "quadruple." These are both adverbs, so "getAdverbOfNumber" won't work. How about getMultiplierAdverb and getOccurrencesAdverb?
