## Lesson: Choosing Formal Vocabulary

You already know that English can sound formal or informal. Today you will build your formal vocabulary: the exact words to use when you write something serious, like a letter or a report. Instead of an everyday phrase, formal writing often uses one precise word.

*(drawing: The everyday phrase 'ask for' becomes the single formal word 'request'.)*

**Example.** Priya texts her friend: 'Just found out the bus is late.' She writes almost the same news in a letter to her school: 'I discovered that the bus service has been delayed.' Same message, two different vocabularies.

**Tip.** Build a bank of formal swaps. 'Ask for' becomes 'request'. 'Enough' becomes 'sufficient'. 'Get' becomes 'receive'. Reach for the single formal word when you write something official.

**Recap.** Formal writing trades everyday phrases for precise words, like request instead of ask for and sufficient instead of enough.
