notable natural landmarks – rivers, seas, mountain ranges, deserts, island groups ( archipelagoes) and so on – are generally used with a 'the' definite article ( the Rhine, the North Sea, the Alps, the Sahara, the Hebrides).Geographic usageĪn area in which the use or non-use of the is sometimes problematic is with geographic names: In Middle English, these had all merged into þe, the ancestor of the Modern English word the. Old English had a definite article se (in the masculine gender), sēo (feminine), and þæt (neuter). The and that are common developments from the same Old English system. The, as in phrases like 'the more the better', has a distinct origin and etymology and by chance has evolved to be identical to the definite article. Definite article principles in English are described under ' Use of articles'.
