Attempts to pluralize or singularize short English phrases.

Does not throw exceptions at present, if you attempt to pluralize an already pluralized phrase, it will leave it unchanged (and vice versa.)

The behavior of this module is subject to change as I tweak the heuristics, as some things get fixed others might regress. The processing of natural language is a messy business.

If it doesn't work, please email or submit to RT the example you tried, and I'll try to fix it.


By default, this module prefers to treat words as nouns (sometimes words can be interpreted as a verb or a noun without context.) This is better for things such as database table/column names, which is what this module is primarily for.

This behavior can be switched with the variable $prefer_nouns. The default is 1.

For example:

    local $Lingua::EN::Inflect::Phrase::prefer_nouns = 0;
    is Lingua::EN::Inflect::Phrase::to_S('sources split'), 'source splits';
    local $Lingua::EN::Inflect::Phrase::prefer_nouns = 1;
    is Lingua::EN::Inflect::Phrase::to_S('source splits'), 'source split';


``to_PL'', ``to_S''
