English nouns that are countable can be plural or singular (mention one or more than one of that thing, person object). Nouns will look different (i.e., use other spelling) based on whether they’re being used as a singular or plural.
Regular nouns will simply add “s” or “es”. Irregular nouns end in something other than “s” or “es”. While this sounds simple enough, because of the amount of nouns there are in English, and the number of irregular noun forms that exist, learning the correct spelling can be difficult.
