writing paper
envelopes
letterhead

greeting cards
invitations

In everyday conversation, some people use stationery broadly for school or office supplies, but the core meaning is writing paper and related materials.

The difference is spelling and meaning, not American vs. British English. Both words exist in both American and British English.

Use this simple test:

> If it can move but currently does not, use stationary. If you can write on it or mail it, use stationery.

The easiest memory trick

Use this memory trick:

An envelope is a common piece of stationery, and both words contain e.

Then remember:

stationary = standing still
stationery = envelopes and paper

This small spelling clue is often enough to avoid the mistake.
