Antonyms trivial

A fundamental or indispensable item, part, or element. When used in the plural ('the essentials'), it refers to the basic requirements or necessities of life or a particular situation. Unlike in English, where 'an essential' or 'the essentials' is commonly used as a noun, Spanish often conveys this concept using adjectives (e.g., 'lo esencial' - the essential thing) or more descriptive noun phrases (e.g., 'los elementos clave' - the key elements) rather than a direct single noun equivalent for 'an essential'.
