Expert writing Tips

Best practice

Use "then by" to clearly indicate a sequence of actions or logical steps, especially in mathematical proofs or procedural explanations. For example, "Assume p. Then by Determinism, □p."

Common error

Avoid using "then by" when a simple "then" or "and then" suffices. Overusing it can make your writing sound overly formal or stilted. For example, instead of "We went to the store, then by the park", prefer "We went to the store, then to the park."
