Description:

Matching multikey words so that english language plurals match singular words is tricky. This function adds more word endings to the original keyword function including irregular plurals and descriptive endings like "ish" (sorry, no adverbs this time around). The function only parses the last word in the string if there are more than one word.

Note: these functions are not guaranteed or supported by BrianDunning.com. Please contact the individual developer with any questions or problems.
