básico

Adjective Agreement
Since 'simples' is an adjective, it must match the thing it describes. Because it ends in '-es', it is used to describe things that are plural, regardless of whether they are masculine (los problemas) or feminine (las reglas).
Using the Singular Form with Plurals
Mistake: “Los problemas es simple.”
Correction: Los problemas son simples. (Remember to use the plural form 'simples' when talking about more than one thing.)
elemental
eh-leh-men-TAHLelemenˈtal

Examples
El agua es un recurso elemental para la vida.
Water is a basic resource for life.
Necesitas aprender las reglas elementales del juego.
You need to learn the basic rules of the game.
Es un derecho elemental de todo ser humano.
It is a fundamental right of every human being.
One Form for All
In Spanish, adjectives that end in 'l' don't change for male or female nouns. You can say 'un paso elemental' (a basic step) or 'una regla elemental' (a basic rule).
Plural Form
To make this word plural, just add '-es' to the end: 'elementales'.
Avoid 'elementala'
Mistake: “una regla elementala”
Correction: una regla elemental. Even though 'regla' is feminine, the adjective 'elemental' stays the same for both genders.
primario
pree-MAH-ryohpɾiˈmaɾjo

Examples
El rojo es un color primario.
Red is a primary color.
Los niños van a la escuela primaria.
Children go to elementary school.

Our primary concern is safety.
Matching the Noun
This word must match the gender of the thing it describes. Use 'primario' for masculine things and 'primaria' for feminine things like 'la escuela primaria'.
Where to put it
In Spanish, this word usually comes after the person or thing you are describing, like 'colores primarios'.
Confusing with 'Cousin'
Mistake: “Calling your cousin 'mi primario'.”
Correction: Use 'primo' for cousin. 'Primario' only describes things that are 'first' or 'basic'.
fundamental
foon-dah-men-TAHLfundaemẽnˈtal

Examples
El respeto es fundamental en una buena amistad.
Respect is essential in a good friendship.
Necesitamos un cambio fundamental en nuestra estrategia.

One Form for All
This word is 'gender-neutral.' Whether you are describing a masculine noun like 'el libro' or a feminine noun like 'la idea,' the word 'fundamental' stays exactly the same.
Plural Pattern
To make this word plural, simply add '-es' to the end: 'los factores fundamentales' or 'las herramientas fundamentales'.
Ending with 'a'
Mistake: “la idea fundamentala”
Correction: la idea fundamental. Even though 'idea' ends in 'a,' words ending in 'l' don't change their ending for feminine words.
estructural
es-truk-tu-RALestɾuktuˈɾal

The architect checked the structural design of the building.

Making it plural
To make this word plural, just add -es to the end. For example, 'los problemas estructurales'.
Avoid adding -a
Mistake: “La reforma estructurala.”
Correction: La reforma estructural. (Words ending in -l stay the same regardless of gender.)
