Abstract
Careless use of certain pronouns in technical writing today causes communication to be a fuzzy and inept as many other writing flaws. The pronouns most commonly misused are the demonstratives, this and that with their plurals these and those ; such relatives as which , who , whom , and that , and the anticipatory expletive it . Eliminating the irritating and confusing aspects of these often misused pronouns is simple. More effective and efficient technical communication will result.
