Children’s dictionaries have come a long way in the last couple of decades. There are electronic options that come in a variety of forms and resemble tiny laptops. We especially love the ones that double as bookmarks! There are also many online options that can be used on a desktop or as an app on a phone or other device. These online options have so many features that we just adore like translation services and even crowdsourced definitions. And don’t worry: We haven’t forgotten about traditional hard-copy dictionaries. Illustrated dictionaries are perfect for the littlest readers, while more advanced options are ideal for older students. We’re sure you will find just what you are looking for in our comprehensive list of the best dictionaries for kids.
