Extremely important and necessary; something that you must have or cannot do without.

Usage & Nuances

Common in both formal and informal contexts. Often used with 'for' ('essential for success') or 'to' ('essential to life'). Not the same as 'necessary'—'essential' is stronger, meaning absolutely required. Used for both concrete things (water, documents) and abstract concepts (skills, qualities).
