Exploring the World of Words: Communicating in Different Languages


Have you ever wondered how many words you need to know in order to communicate effectively? It’s a fascinating question that has been explored by linguists and language enthusiasts alike. While the answer may vary depending on factors such as language background and education, one thing is clear: words are the building blocks of communication.

The Complexity of Words

Determining the exact number of words a person knows can be challenging. Should variations of a word, such as “run” and “running,” be counted separately? What about words with multiple meanings or those that can function as both nouns and verbs? These complexities make it difficult to provide a definitive answer.

For the purpose of this discussion, we will consider word families. Word families include related words, such as “run,” “ran,” and “running,” which are all derived from the same root word. Counting word families provides a more comprehensive understanding of vocabulary knowledge.

The Power of Word Families

Research has shown that even though we may know tens of thousands of words, we tend to use a relatively small percentage of them in everyday conversations. In fact, the first two thousand most frequently used words make up approximately 90% of spoken communication and 80% of written articles[^1^]. This suggests that mastering a core set of word families is essential for effective communication.

Learning a foreign language, for example, requires a solid foundation of around 2,000 word families to navigate daily situations[^1^]. Don’t let the seemingly large number intimidate you; it’s within reach with the right approach.

My Journey with English

Having studied English for over three years, I estimate that I am familiar with about 10,000 word families. My estimation is based on assessments found on language proficiency websites and my recognition of common word lists[^3^]. While this number may fall short of a native speaker’s vocabulary, it covers more than 98% of the content I encounter in my reading.

To further expand my vocabulary, I immerse myself in topics that genuinely interest me. By extensively reading materials related to my passions, I expose myself to a wide range of words and phrases. This approach allows me to learn new words naturally through context, which has proven to be effective for me. Additionally, I utilize Anki, a digital flashcard app, to store essential words for regular review.

Embracing Language Learning
