Summary about compound noun
A compound noun is a noun that has more than one root.
In juxtaposition, the union between the elements of the compound noun occurs, without changing any of them.
In agglutination, there is a fusion between the elements of the compound noun, with an alteration of one of them.
The compound noun may or may not have a hyphen, according to the rules for using this graphic sign.
Unlike the compound noun, which has more than one radical, the simple noun has only one radical.
There are other types of nouns, namely: common, proper, primitive, derived, concrete and abstract.
