Dictionaries have always been a great source of knowledge and information for young students, but today, as educational standards in many states call for greater achievement in reading and language skills, dictionaries have become an indispensable tool for students.

Merriam-Webster dictionaries are written to reflect the abilities and understanding of specific age groups and reading levels. Word lists contained in each volume are based on Merriam-Webster editors’ ongoing research into vocabulary for individual grade levels.
