Sometimes a linguistic element can refer back to more than one antecedent. Newcomers to a subject are especially likely to trip by assuming reference to the wrong antecedent. This happens to me all the time when I am reading. So when I am writing I often start an anaphora with a repetition of an antecedent term. I believe this will make it easier for some of my readers.

I also add bulk to my drafts by replacing pronouns with proper names. I do this wherever a reader, who may not as familiar with the named entities as I am, might get them confused.
