Expert writing Tips

Best practice

Place the phrase at the beginning of a sentence, followed by a comma, to clearly signal a transition to the reader.

Common error

Avoid using "What's more" simply to list items of equal importance. Its primary strength is adding 'weight' or emphasis to a subsequent point. If the points are merely sequential without an increase in importance, consider using "<a href="/s/additionally" target="_blank" rel="alternative">additionally" or "<a href="/s/also" target="_blank" rel="alternative">also" instead.

Linguistic Context

The phrase "What's more" functions as a conjunctive adverbial phrase. Its primary role is to serve as a transition between two independent ideas, where the second idea expands upon or intensifies the first. According to Ludwig AI, the phrase is almost exclusively used at the start of a sentence or clause to signal that the writer is about to provide further evidence or a more compelling argument.
