Countable nouns generally have singular and plural forms. In most cases the plural is formed from the singular by adding "-s" (as in "dogs", "bushes"), although there are also irregular forms ("woman/women", "foot/feet", etc.), including cases where the two forms are identical ("sheep", "series"). For more details, see English plural. Certain nouns can be used with plural verbs even though they are singular in form, as in "The government were ..." (where "the government" is considered to refer to the people constituting the government). This is a form of synesis; it is more common in British than American English. See .
