That Darned Squiggly Thing

If there's one thing that's inconsistent in business writing, it's the use of the ampersand (&). If you must use this thing, do you know when it's appropriate? In our abbreviation-happy world, the answer can be elusive. See if you know.

In formal business writing, ampersands are correct to use in place of "and" in what cases?

1. All cases

2. Related words (roads & bridges)

3. Names of companies or works

4. No cases

And the correct option is the third one. In Associated Press style and business writing, an ampersand is correct to use when it’s part of a company's name (Procter & Gamble, Johnson & Johnson) or the title of a work (Willy Wonka & the Chocolate Factory; Eats, Shoots & Leaves). Otherwise, besides in a few colloquial business-jargon abbreviations (R&D, M&A), the ampersand should not be used in place of “and.” However, many writers subconsciously shift to an ampersand when they encounter two or more related terms (sales & marketing, revenues & profits). This is incorrect and introduces notable inconsistency in a communication, where “and” is likely spelled out in other places. Please, don’t do it.
