Usage notesEdit

In English, the plural suffix “-es” is productive because it can be appended to an open set of words (singular nouns ending in sibilants). Thus, if a new word with that pattern becomes an English noun (e.g. *examplex), it would have a default plural (e.g. *examplexes) because “-es” is productive.
