15 Complex - Anticipation (Subordinates only) “Whenever people are short on ideas they tend to use long words.”
If Anticipation (dependent clause) is short and relationship to the independent clause is obvious, consider omitting the usual comma. Momentum is improved if you exploit the principle of open punctuation whenever ease of reading and understanding is not likely to be affected. This could have been “ideas, they” but brevity would be lost. Clauses are very closely related, and brevity of anticipation makes it easier.
