Relative pronoun. The pronouns “that,” what whatever which “whichever,” “who,”and whoever link dependent clauses to sentences and suggest a relationship between the clause and the main statement. Relative pronouns operate quite straightforwardly in sentences and clauses The lion is the biggest cat that lives in Africa “Smithers is the hunter who shot a lion.” “Kunga is a lion who eats whomever it can nd.” The relative pronouns change case (and sometimes form, depending on how they are used in their clauses. Thus “who” is the subjecttwice in the example sentences, while whomever is the object of “finds.” Agreement of relative pronoun subjects and their verbs or other pronouns that refer to them also follows expected rules and patterns. However, take care with the combination of one and who It is sometimes tricky to tell whether the “who” following a one refers to a singular or plural antecedent. The verb that follows “who” needs to be in the correct number in these instances, of course, so the antecedent must be checked Appleton is the one who baked the bread Who is singular because Appleton is only one person. But Appleton is one of those who bake bread Here who refers to “those”—the many people who bake bread—and therefore the verb is plural. Many sentences are not so obvious as these examples, and errors in agreement between who and a verb are common. Repetition.One device of persuasion or emphasis is repetition—using the same word, phrase, clause, order of words,sentence structure, voice, mood, or other feature of writing more than once to make a point or call attention to something. If you choose to employ repetition in your writing, take care to maintain some degree of consistency or parallelism among repeated elements so that your audience can easily recognize them. However, repeating a simple sentence structure like a noun followed by a verb or adjectivecan dispel all the rhetorical force built up by repetition.
