My wife spotted this on an envelope.

Problem:
The contraction is missing an apostrophe.

Explanation:
“WERE MOVING OR HAVE MOVED!” was stamped in red beneath a business’s old address in the return-address section of an envelope.

The business obviously had a lot of envelopes that had been printed with its old address in the return-address section, and beneath that section the business had stamped a new message in red to let envelope recipients know one of the following:

• The business was in the process of moving.
• The business had already moved.

The new address appeared — also in red — beneath “WERE MOVING OR HAVE MOVED!”, so that envelope recipients would have the new address of the business.

The problem with the red-stamp headline is that it is missing an apostrophe.

When one creates a contraction — in this case from the pronoun “WE” plus the verb “ARE” — an apostrophe must be included to indicate the letter or letters that one has removed to create the contraction.

I believe that the omission of the apostrophe is consistent with my “Devolution toward Simpler” linguistic hypothesis. It is simpler to omit an apostrophe than to include one.

Solution:
“WE’RE MOVING OR HAVE MOVED!”
