Expert writing Tips
Best practice
Use "and then certainly" to clearly indicate a sequence of events where the second event is a predictable or logical outcome of the first. It adds emphasis to the certainty of the subsequent action.
Common error
Avoid using "and then certainly" in situations where the sequence is obvious and the emphasis is unnecessary. Overusing it can make your writing sound redundant or overly formal. Opt for a simpler "and then" if the certainty is already implied.
