Formal vs Informal Words

🎩 Formal vs Informal Language in English – A Complete Guide

Understanding the difference between formal and informal language is fundamental to effective communication in English. In linguistics, this distinction is called register — the level of formality used depending on context, audience, and purpose. Choosing the right register demonstrates linguistic competence and is a key assessment criterion in English exams at VGS level.

🔬 The Linguistic Background: Why Does English Have Two Registers?

English is unique because it draws vocabulary from two main sources:

• Germanic roots (Old English / Anglo-Saxon): These are the everyday, informal words. They tend to be shorter and more concrete — help, buy, start, end, die, eat.
• Latin/French roots (via the Norman Conquest, 1066): These are the formal, academic words. They tend to be longer and more abstract — assist, purchase, commence, terminate, decease, consume.

After the Norman Conquest of England in 1066, French-speaking Normans ruled over English-speaking commoners. Over time, English absorbed thousands of French and Latin words, which became associated with education, law, government, and the upper classes — hence their formal register.

📝 Formal vs Informal Sentence Structures

Register is not just about individual words — sentence structure also changes between formal and informal English.

Key Structural Differences

📖 Extended Examples in Context

Example 1: Requesting something

Formal:

"I am writing to request further information regarding the application process. I would be grateful if you could respond at your earliest convenience."

Informal:

"Hey, can you tell me more about how to apply? Get back to me when you can!"

Example 2: Describing a problem

Formal:

"The investigation revealed that insufficient funding had contributed to the deterioration of public services."

Informal:

"They found out that there wasn't enough money, and that made things worse."

Example 3: Giving an opinion

Formal:

"It is evident that climate change constitutes a significant threat to global biodiversity. Furthermore, the scientific community has demonstrated that immediate action is imperative."

Informal:

"It's obvious that climate change is a big problem for animals and nature. Also, scientists have shown that we need to act now."

💡 Exam Strategy: Choosing the Right Register

• Argumentative essays and articles: Use formal register consistently. Avoid contractions, slang, and phrasal verbs. Use hedging language ("It could be argued that…", "Evidence suggests that…").
• Creative writing: Match register to the character and context. A teenager's inner monologue should be informal; a narrator's description can vary. Dialogue should sound natural.
• Analysis and discussion texts: Use formal register with precise analytical vocabulary ("The author employs…", "This device serves to…", "The text conveys…").
• Emails and letters: Adjust to audience. A letter to the editor = formal. An email to a classmate = informal.

📌 Pro tip: Mixing registers in an essay is a common mistake. If you start formally, stay formal throughout. Consistency demonstrates control of language.

Academic Deep-Dive

To write at a high academic level, move from description to analysis. That means you should explain why an example matters, how it connects to the theme, and what broader consequences it may have for individuals, communities, or policy.
