Irregular Pluralization

Nouns come in a singular form (when you are talking about one of something) and a plural form (when you are talking about more than one of something). Most nouns can be pluralized by adding an "s" to the end of the noun in one way or another: 


		SINGULAR			PLURAL

		 swing				 swings
		 pretzel			 pretzels
		 mask				 masks
		 valley				 valleys
		 fly				 flies
		 beaver				 beavers
		 trapper			 trappers
		 inch				 inches
Some nouns are pluralized without adding an "s" to the end of the noun. These nouns are considered irregular in the way they are pluralized. 

		SINGULAR			PLURAL

		 goose				 geese
		 mouse				 mice
		 foot				 feet
		 louse				 lice
		 tooth				 teeth
		 man				 men
		 sheep				 sheep
		 deer				 deer
You should notice that the plural and singular forms of "sheep" and "deer" are the same. This can be confusing at times.
