The cabbage white butterfly lays its eggs on members of the Brassica genus.
However, recent developments show that definite articles are morphological elements linked to certain noun types due to lexicalization. Under this point of view, definiteness does not play a role in the selection of a definite article more than the lexical entry attached to the article.[clarification needed]
The definite article is sometimes also used with proper names, which are already specified by definition (there is just one of them). For example: the Amazon, the Hebrides. In these cases, the definite article may be considered superfluous. Its presence can be accounted for by the assumption that they are shorthand for a longer phrase in which the name is a specifier, i.e. the Amazon River, the Hebridean Islands. Where the nouns in such longer phrases cannot be omitted, the definite article is universally kept: the United States, the People’s Republic of China. This distinction can sometimes become a political matter: the former usage the Ukraine stressed the word’s Russian meaning of “borderlands”; as Ukraine became a fully independent state following the collapse of the Soviet Union, it requested that formal mentions of its name omit the article. Similar shifts in usage have occurred in the names of Sudan and both Congo (Brazzaville) and Congo (Kinshasa); a move in the other direction occurred with The Gambia.
