* English uses definite articles ("the") before singular and plural nouns, but indefinite articles ("a" or "an") are only used before singular nouns.
* Example: "The dog" and "The dogs" are correct, but only "a dog" is correct.
* Spanish uses definite articles ("el", "la", "los", "las") before all nouns, both singular and plural.
* Example: "El perro" (the dog) and "Los perros" (the dogs) are both correct.
This difference can lead to confusion for learners of both languages, as it requires adjusting how articles are used based on the language.
