200+ Formal and Informal Words List in English | Download PDF

Language is an essential tool for communication. However, the way we use language can vary depending on the context and the audience. In particular, the choice between formal and informal words can significantly impact how our message is perceived. Formal language is typically used in professional or academic settings, while informal language is more appropriate in casual conversations or personal interactions.

In this blog post, we will explore the differences between formal and informal words and provide examples of when to use each one. Whether you’re writing an email to your boss or having a conversation with a friend, understanding the nuances of formal and informal language can help you communicate more effectively.

Difference between formal and informal words

Formal

Formal words are typically used in professional or academic settings, such as in business, legal, or technical writing. These words tend to be more precise, specific, and sophisticated in their meaning and tone and are often chosen to convey a sense of professionalism, authority, or formality.

Informal

Informal words, on the other hand, are typically used in casual or social settings, such as in everyday conversations with friends or family members. These words tend to be more colloquial, relaxed, and familiar in their meaning and tone and are often chosen to convey a sense of friendliness, humor, or informality.

Here are some examples of formal and informal words:

Formal:

• commence (start)
• terminate (end)
• subsequently (later)
• facilitate (help)

Informal:

• start (commence)
• end (terminate)
• later (subsequently)
• help (facilitate)

As you can see, formal words are more complex and less common in everyday speech, while informal words are simpler and more commonly used in casual conversations. It’s important to be aware of the context and audience when choosing which type of language to use.
