Expert writing Tips

Best practice

Use "only then did" to clearly establish a sequence of events where the second event is contingent on the first. For example: "The rain stopped; only then did the sun appear."

Common error

Avoid using "then only did" as it reverses the emphasis and is grammatically awkward. The correct form, "only then did", maintains the focus on the condition preceding the action.
