Look at the sentence below and explain in English why the underlined portion is incorrect.

Question

El la una bandera está al lado de la puerta.

Answer 1

The underlined portion "el la una bandera" is incorrect because it is a combination of three different articles ("el," "la," and "una") that are used to indicate different genders and quantities of the noun "bandera" (flag). In Spanish, only one article should be used at a time to modify a noun.
