People with significant linguistic intelligence are often good at languages and enjoy reading and writing.
For example
A student with strong linguistic intelligence may remember new words very easily and use them quickly.
In the classroom
Supporting and developing linguistic intelligence involves encouraging learners to enjoy real communicating through reading and writing, and speaking and listening. This allows learners to see the purpose of language, and helps them take an interest in it. Writing and receiving real letters or emails from classmates or e-pals is motivating, as are any group communicative speaking activities.
