We offer three powerful ways to learn spelling words for those looking for "":


1 – Select goal “improve vocabulary and/or spelling” 


This will take you our linguistic data stream by grade level, featuring thousands of must-know words per grade. These words are sorted difficulty,  so you advance from easy to advanced automatically.


We also offer another goal setting: "My own list of words." With this preference selected, your sessions will end once all added words and all practice words have been reviewed. LTW will not suggest additional words.



2 – Find spelling word lists in our archive


Whatever glossary or spelling word list you're looking for, chances are we already have it in our word list archive for one-click tutoring—and the archive is constantly growing!



3 – Add your own word list


Adding your own words to your own account or a classroom is very easy. You can even add custom definitions!
