The most important distinction between nouns in English is between countable and uncountable. Other languages such as Spanish also have this: bebida is a countable noun. You can have una bebida (one drink) or dos bebidas (two drinks). 

Common uncountable nouns include information, money, happiness, love, transportation, and many other abstract nouns. 

Most times, countable and uncountable are the same in English and Spanish. However, there are a few difference. In English, homework (tarea) is uncountable. You cannot have two homeworks. 

In 90% of cases, to make a noun plural in English, you simply add an s. Sometimes, you have to add an -es, like in the words churches (church), boxes (box) or glasses (glass). There are very few irregular plural nouns (demonstrated in the image), such as children, mice, or feet.
