That? Which? Or What?

That? Which? Or What?

By Philip B. Corbett

After Deadline examines questions of grammar, usage and style encountered by writers and editors of The Times.

It is adapted from a weekly newsroom critique overseen by Philip B. Corbett, the deputy news editor who is also in charge of The Times’s style manual. The goal is not to chastise, but to point out recurring problems and suggest solutions.

Since most writers are likely to encounter similar troubles, we think these observations might interest general readers, too.
