Understanding the Verb: Desensitise
Have you ever watched a scary movie and realized that the jumps and shocks didn't frighten you as much as they used to? Or perhaps you have noticed that after living near a busy train station for a few months, you no longer wake up when a train passes by at night? In these scenarios, you have become desensitised to your environment. To desensitise means to reduce the emotional or physical response to a specific stimulus, making something that once felt intense or shocking feel completely ordinary.
Definitions and Core Meanings
At its core, the word desensitise (or desensitize in American English) describes the process of making something less sensitive. This can apply to physical sensations, such as pain or light, or emotional states, such as fear, anger, or empathy.
- Causing a loss of physical sensitivity: This often relates to medicine or biology, where a treatment might reduce an allergic reaction or make a part of the body less reactive to pain.
- Making someone emotionally insensitive: This is the most common usage in social commentary. It describes how repeated exposure to violence in media or difficult living conditions can make a person less reactive to suffering or shock.
Grammar and Usage Patterns
Desensitise is a transitive verb, which means it usually requires an object—the person or thing being affected. Here are the most common ways to structure the word in a sentence:
Common Patterns:
- Desensitise + someone/something + to + noun/gerund: This is the classic construction. You are desensitising a subject to a specific stimulus.
- Example: "Constant exposure to violent video games can desensitise teenagers to real-world aggression."
- Example: "The cream helps to desensitise the skin to heat and cold."
Because the word implies a change over time, you will frequently see it used in the passive voice or in the continuous tense.
- Passive: "The public has been desensitised to the news of political scandal."
- Continuous: "The loud noise of the construction site is slowly desensitising the neighborhood to the sound of sirens."
Common Mistakes
When learning this word, students often confuse it with "insensitive." While they are related, they serve different functions:
- Confusing the adjective and the verb: Desensitise is the action, while insensitive is the state of being. You cannot "be insensitive" to something in the same way you "desensitise yourself" to it. Use the verb for the process and the adjective for the result.
- Spelling differences: As mentioned, desensitise is the British English spelling, while desensitize is the American English spelling. Both are correct, but it is best to stay consistent with one style throughout your writing.
- Forgetting the preposition: A common error is omitting the word "to." Always remember that you are desensitising someone to something.
Frequently Asked Questions
Is desensitise always negative?
Not necessarily. While it is often used to describe negative social trends (like becoming desensitised to violence), it can be positive in medical contexts. For example, doctors might work to desensitise a patient to a specific allergen, which helps the patient lead a healthier life.
Can I use desensitise for objects?
Yes, though it is less common. You might use it in a technical or scientific sense, such as desensitising photographic film or a chemical sensor so that it does not react too strongly to light or heat.
What is a good synonym for desensitise?
If you want to vary your vocabulary, you can use words like numb, harden, dull, or inure. For example, "The harsh winter weather began to inure them to the freezing cold."
Conclusion
The word desensitise is a powerful tool for describing how we adapt to the world around us. Whether we are discussing psychological reactions to media, medical treatments for allergies, or the way we grow accustomed to our daily environment, the word captures the transition from high reactivity to a state of calmness or indifference. By understanding how to use it correctly—remembering the "to" preposition and the difference between the process and the state—you will be able to describe these nuanced changes in human behavior and physical reactions with greater precision.
