require
Cannot do without
Require means to need or to demand as necessary.
A job may require certain qualifications; a recipe requires specific ingredients.
In formal or legal contexts, require indicates obligation: Passengers are required to wear seatbelts.
The word carries more weight than need—what's required isn't optional.
This requires your immediate attention.
