Top 5 Reasons Why Vocabulary Matters

There has been a big push the last 10-15 years to improve students’ vocabulary skills, but do you know why?

Here are the top 5 reasons why vocabulary is so important:

1 It Improves Reading Comprehension.

Research has shown that kids need to understand 98% of the words they read to understand what they are reading. Improving vocabulary skills will improve their understanding of novels and textbooks.


2 It’s Important to Language Development.

Children who develop a rich vocabulary tend to be deeper thinkers, express themselves better and read more. Improving language and literacy skills early in life will help them be more successful academically and communicatively.


3 Communicating Ideas.

Successful communication or “saying what you mean” is dependent upon a good vocabulary base. Using the right words when talking, makes you a more effective communicator.


4 Expressing Yourself in Writing.

Having a good vocabulary to draw from can help you write more effectively. Students need to use a more formal tone when writing – not conversational language – and to do that, they need a richer vocabulary to tap into those words we don’t use when we speak.


5 Occupational Success.

Researcher Johnson O’Connor found that “a person’s vocabulary level is the best single predictor of occupational success.”* Success in the business place depends on your communication skills.
