essential

/ɪˈsɛn.ʃəl/

When used as an adjective, "essential" often takes the preposition "to" (e.g., essential to the process) or "for" (e.g., essential for survival). As a noun, it is most commonly used in the plural form ("essentials") to describe a group of basic things you need for a specific purpose, such as 'travel essentials'. Avoid using "essential" and "very important" together in the same phrase, as "essential" already implies the highest level of importance.
