Irregular Plurals is the thirty-fourth skill of the French language tree. In this skill, you learn how to form irregular plurals in French (as the name of the skill implies), through a series of three lessons.

Grammar NotesEdit

As you may have noticed in the words in this skill there is usually an -x following the irregular plural. You usually add an -x if there is an -eau, an -ou, -au, or an -eu ending. (An exception to this would be bleu - the plural is bleus)

However, if there is an -eil, an -al, or an -ail at the end of the word, you usually drop the -l or -il part of the word and add -ux instead.

A notable exception is œil (plural=yeux). There is no explanation for this except that the French word happened to evolve that way.
