Definite and Indefinite articles

Here are 2 lessons on the definite and indefinite articles in Spanish. The definite articles are "el", "la", "los" and "las". When translated, these words mean "the", but are categorized in masculine/feminine, and singular/plural. You can also use indefinite articles, which follow the exact same concept, but instead of use "un" for "el", "una" for "la", "unos" for "los" and "unas" for "las". The difference is that instead of meaning "the" the indefinite articles mean "a/an" or "some".
