More about fauna
Fauna “the animals of a given region as a whole” is an example of a collective noun, a noun that typically appears as singular but refers to a group of persons or objects. Common collective nouns in English also include couple, government, jury, population, and team, all of which refer to groups of people even when the nouns themselves are singular. Unlike mass nouns such as electricity, furniture, and sadness, collective nouns can use the indefinite article a (or an) and numbers; we may say a team or two couples but not an electricity or two furnitures. Fauna is the namesake of the rural Roman goddess Fauna, the feminine counterpart of the forest god Faunus. These two Latin names may come from the verb favēre “to favor,” which would make them potential relatives of the recent Words of the Day Faustian and foehn. Fauna was first recorded in English circa 1770.
