Word of the day: What 'pernicious' means and how to use it right

The Word of the Day is pernicious. It is a strong and impactful word used to describe something that causes serious harm, often slowly and in a way that is not immediately obvious.

In everyday use, pernicious is often linked to harmful habits, dangerous ideas, or negative influences that grow over time.

WHAT DOES PERNICIOUS MEAN?

Pernicious is an adjective. It means very harmful or damaging, especially in a gradual or hidden way.

In simple words, something pernicious may not look dangerous at first, but over time it creates serious damage. It is often used to describe effects that spread quietly but have a long-lasting negative impact.

For example, misinformation, addiction, or toxic behaviour can all be described as pernicious because their harm builds slowly and steadily.

HOW TO USE PERNICIOUS IN SENTENCES

This word is commonly used in formal writing, news reports, and analytical discussions. It helps describe hidden or slow-building harm.

Here are some examples:

• “Social media can have a pernicious effect on self-esteem.”

• “The policy had a pernicious impact on rural education.”

• “He warned about the pernicious influence of misinformation.”

• “Smoking has long-term pernicious effects on health.”

These examples show how the word is used to highlight deep but often unnoticed harm.

MAKE YOUR LANGUAGE MORE PRECISE

Instead of saying: “This is very harmful,”
You can say: “This has a pernicious effect.”

Using pernicious helps you sound more precise and thoughtful. It is especially useful when describing problems that do not appear dangerous immediately but become serious over time.
