Mastering Style and Tone

On the ACCUPLACER Writing test, you are often asked to evaluate passages based on their style and tone. While grammar provides the rules for constructing sentences, style and tone dictate how those sentences feel to the reader. Choosing the right words and structures to match the intended audience and purpose is a critical writing skill.

Defining Tone and Style

Tone refers to the writer's attitude toward the subject matter or the audience. Tone can be formal, informal, serious, humorous, sarcastic, objective, or passionate. Style encompasses the choices a writer makes regarding vocabulary, sentence structure, and overall presentation. Style is how the tone is delivered. In most academic and professional contexts (and therefore, on most standardized tests), the expected tone is objective and formal, and the style is clear and direct.

Formal Academic Diction

Diction refers to word choice. Formal academic diction involves selecting words that are appropriate for serious, scholarly writing. This means avoiding slang, colloquialisms, idioms, and overly casual language.

Informal DictionFormal Academic DictionWhy it matters
The researchers looked into the problem.The researchers investigated the problem.'Looked into' is colloquial; 'investigated' is precise and professional.
The results were totally awesome.The results were highly significant.'Totally awesome' relies on slang and subjective emotion.
The author talks about the economy.The author discusses the economy.'Discusses' or 'analyzes' is more appropriate for academic analysis.
The company went belly up.The company declared bankruptcy.'Went belly up' is an idiom; formal writing requires literal accuracy.

Identifying Shifts in Tone

A frequent error in writing is a jarring shift in tone. This happens when a writer establishes a formal, objective tone but suddenly uses slang or highly emotional language. On the exam, you must spot these inconsistencies and choose revisions that restore a unified tone.

Example of a Tone Shift: The sociological study meticulously detailed the demographic changes in the urban center over the last decade. It's crazy how fast the neighborhood gentrified.

The first sentence is highly formal ('meticulously detailed', 'demographic changes'). The second sentence suddenly shifts to a casual, conversational tone ('It's crazy how fast').

Corrected Version: The sociological study meticulously detailed the demographic changes in the urban center over the last decade. The data reveals a rapid pace of gentrification. This revision maintains the objective, academic tone throughout.

Avoiding First and Second Person Pronouns

In formal academic writing, it is generally best to avoid first-person pronouns (I, me, my, we, us) and second-person pronouns (you, your). These pronouns make the writing sound personal, conversational, or instructional, which detracts from an objective tone.

  • Informal/Subjective: I think that the protagonist is unreliable. You can see this in chapter four.
  • Formal/Objective: The protagonist's unreliability is evident in chapter four.

Instead of stating 'I think' or 'I believe', state the argument directly based on the evidence.

Objective vs. Subjective Language

Academic writing strives for objectivity, meaning it relies on facts, evidence, and logical analysis rather than personal feelings, opinions, or emotional appeals (subjectivity).

  • Subjective: The terrible policy unfairly punished poor people.
  • Objective: The policy disproportionately affected lower-income demographics.

The objective version removes the emotional adjectives ('terrible', 'unfairly') and replaces them with precise, measurable terms, making the argument stronger and more credible.

Passage-Based Revision Example

Original Passage: The synthesis of the new compound requires a controlled environment, specifically regarding temperature and humidity. If you mess up the temperature even a little bit, the whole batch goes down the drain. Therefore, strict adherence to the protocol is mandatory.

Question: Which choice best maintains the tone established in the passage? Options:

  • A) If you mess up the temperature even a little bit, the whole batch goes down the drain.
  • B) A minor deviation in temperature will result in the complete failure of the batch.
  • C) Getting the temp wrong ruins the entire thing.
  • D) It's super important not to screw up the temperature, or else.

Breakdown: The passage begins and ends with formal, scientific language ('synthesis', 'controlled environment', 'strict adherence', 'mandatory'). The middle sentence, however, uses highly informal slang ('mess up', 'goes down the drain'). Option B is the only choice that replaces the slang with formal vocabulary ('minor deviation', 'complete failure') that matches the surrounding text. Options C and D introduce new informalities ('temp', 'screw up', 'super important').

Strategies for the Exam

  1. Identify the Baseline Tone: Read the entire passage to determine its overall purpose and audience. Is it a scientific report, a historical analysis, or a personal narrative?
  2. Spot the Outlier: Look for words or phrases that stick out because they are too casual, too emotional, or rely on cliches and idioms.
  3. Choose Consistency: When selecting a replacement, ensure the new word or phrase matches the baseline tone in both vocabulary and structure.
