Imperative

Simple meaning

Imperative means absolutely essential and urgent — something that must be done and cannot be put off or ignored.

Detailed meaning

Imperative comes from the Latin imperare — to command. In English, it is used in two ways:

As an adjective: absolutely necessary, must be done. "It is imperative that we address this immediately."

As a noun: something that is an absolute requirement — a must. "Safety is an imperative in this industry."

In grammar: the imperative is the verb form used for commands and instructions. "Stop. Listen. Write your name." — these are imperatives.

The common, everyday meaning is the adjective and noun uses — something so important it cannot be deferred. It is stronger than necessary or important. If something is imperative, there is no room for delay or avoidance.

Where to use it

It works well in:

• Urgent communications — "It is imperative that..."
• Strategic priorities — "speed is an imperative in this market"
• Reports and formal writing — "the imperative to reduce carbon emissions"

Where not to use it

Imperative is a strong word — it signals no option, no delay. Don't use it for things that are merely useful or recommended.
