What it is

The practice of ending sentences with prepositions, which is grammatically acceptable in modern English despite traditional prohibitions, especially when avoiding it creates stilted or unnatural phrasing in professional communication.

Before

“Overly formal: "About what are you concerned?" (stilted)”

After

“Natural usage: "What are you concerned about?" (conversational and clear)”

When you’ll use it

Client meetings: "Which project are you working on?" (natural vs "On which project are you working?")

Team discussions: "What are we waiting for?" (natural vs "For what are we waiting?")

Performance reviews: "What should we focus on?" (natural vs "On what should we focus?")

Strategic planning: "Which market are we competing in?" (natural vs "In which market are we competing?")

Choose the version that sounds more natural to your audience.
