The is the definite article of the English language that means “the”, “the”, “the”, “as”. To define a noun of any gender or number, just use a single article. For example: the man (The man), the woman (the woman), the men (men), the women (the women).
“The” is, therefore, an invariable article in the English language. It is used before feminine, masculine, singular or plural nouns to specify the being (or beings) being spoken of.
The article “the” should be used after a person's name and before an adjective that characterizes him, for example, "Alexander the Great" (Alexander, the Great), "jack the ripper” (Jack the Ripper), etc.
It should also be used before proper names of buildings, ships and others, for example, “the Empire State Building”, “the Titanic”, etc. Or in front of the name of a person who wants to be distinguished from another, for example, “I´m sure that wasn´t the Maria we know" (I'm sure she wasn't The Mary we know).
In English, the indefinite articles “a” and “an” are designated by “a” (used before
sounds of consonants) or “an” (used before sounds of vowels). For example: the dog (a dog), the table (a table), an umbrella (a umbrella), an honor (an honor).
