The English lexicon may be broken into 8 categories, based on different uses or parts of speech. These eight categories are: adjectives, adverbs, conjunctions, determiners, nouns, prepositions, pronouns, and verbs.
English does not assign gender grammatically.
Nouns are sub-categorized in the following categories: proper (John, Persia), common (snake, lemonade), sensory (touch, look) and abstract nouns (cowardice, anger). A further distinction is made between countable (oranges, shirts) and unaccountable nouns (milk, water). There also exists a crossover, nouns which are both countable and uncountable (dinner/dinners).
Countable nouns are made into plurals, most often, by the addition of –(e)s (plums, peaches). Another method is used for irregular forms (man/men, woman/women). Occasionally nouns will use the same form for both singular and plural (sheep, fish).
Nouns in the English language take the possessive form to show ownership. This is achieved by the addition of: -'s (Mary's, people’s). Multiplicity of ownership is indicated by the addition of the apostrophe after the word (dogs’ owners). Possession can be shown in two common ways; as the determiner (Tom's cat), and also as a noun phrase (Tom's is the red car).
