Lingua::EN::Inflect is a Perl module which can pluralize words in English. It
 handles the special cases, and support nouns, verbs, and adjectives. It can
 also pick between "a" and "an" based on pronunciation of a word and compare
 words in a "number-insensitive" manner.
 .
 Lingua::EN::Inflect follows the Oxford English Dictionary and the guidelines
 in Fowler's Modern English Usage, preferring the former where they disagree.
 Both British and American English are supported.
