Focus on example sentences when learning vocabulary. Here's why?

When it comes to learning English vocabulary, the most important thing you need to focus on is example sentences because they help you to improve all your English skills - including vocabulary, listening, speaking, and writing.

• Vocabulary: Example sentences help you understand the meaning of the word correctly, and remember it deeply. Why? Because you see the word in context.
• Speaking/Writing: You will learn how to use a word in sentences — how to connect it with other words to produce correct English sentences. For each sentence you hear or read, you will be able to re-use it (or part of it) to produce your own correct sentence.
• Grammar: You learn English grammar naturally. You don’t have to think about grammar rules to produce a sentence. Phrases and sentences just appear naturally in your mind and they are all correct. You “feel” grammar, just like a native English speaker.
