Principles of Clear Writing · Sentence Structure and Common Sentence Errors
Clear writing presents one idea per sentence, uses simple sentence structures when possible, and avoids unnecessary complexity. The goal is to transmit information, not to display elaborate vocabulary or complicated sentences.
Directness
Direct sentences state the subject first, follow with the verb, and end with the object or complement. This subject-verb-object pattern matches how readers process information. Compare the indirect "It was determined by the officer that the suspect had fled the scene" with the direct "The officer determined that the suspect had fled the scene." The direct version names the actor at once and uses fewer words.
Conciseness and Redundancy
Conciseness removes unnecessary words without losing meaning. Wordy phrases dilute impact and slow comprehension. Redundant expressions repeat a meaning that is already there: "advance forward" is redundant because advance already means forward movement.
| Instead of | Write |
|---|---|
| due to the fact that | because |
| at this point in time | now |
| in the event that | if |
| for the purpose of / in order to | to |
| past history | history |
| completely unanimous | unanimous |
| revert back | revert |
| close proximity | proximity / near |
| end result | result |
| free gift / added bonus | gift / bonus |
Avoiding Ambiguity
Ambiguity occurs when a sentence permits more than one interpretation. In law enforcement writing it creates legal problems and miscommunication.
Sentences must be complete and correctly joined. Knowing the four sentence types helps you see when a sentence is broken.
| Type | Structure | Example |
|---|---|---|
| Simple | One independent clause | The officer arrested the suspect. |
| Compound | Two independent clauses joined by a comma and coordinating conjunction, or by a semicolon | The officer arrested the suspect, and the suspect confessed. |
| Complex | One independent clause and at least one dependent clause | After the officer arrested the suspect, the suspect confessed. |
| Compound-complex | Two or more independent clauses and at least one dependent clause | After the officer arrested the suspect, the suspect confessed, and the case was closed. |
Fragments
A fragment lacks a subject, a verb, or a complete thought. "Running through the alley" lacks a subject. "The suspect in the blue jacket" lacks a verb. "Because the witness refused to testify" is a dependent clause with no independent clause to attach to. Fragments on the exam often appear as a second "sentence" that begins with because, although, which, while, or an -ing word.
Run-ons and Comma Splices
A run-on (fused sentence) joins two independent clauses with no punctuation: "The suspect fled the officer pursued." A comma splice joins them with only a comma: "The suspect fled, the officer pursued." Words such as however, therefore, and then do not fix a comma splice, because they are not coordinating conjunctions.
| Method | Example |
|---|---|
| Comma + coordinating conjunction (for, and, nor, but, or, yet, so) | The suspect fled, and the officer pursued. |
| Semicolon | The suspect fled; the officer pursued. |
| Semicolon + conjunctive adverb + comma | The suspect fled; however, the officer caught him. |
| Two sentences, or make one clause dependent | The suspect fled. When the officer pursued, ... |
Misplaced and Dangling Modifiers
Misplaced modifiers sit next to the wrong word: "The officer chased the suspect wearing body armor." Who wore the armor? Place the modifier beside what it describes: "The officer wearing body armor chased the suspect." Dangling modifiers have nothing logical to describe: "Running through the alley, the weapon was found." Weapons do not run. Correct it by naming the actor: "Running through the alley, the officer found the weapon."
