This really slim electronic dictionary bookmark is a logophile (which means lover of words for you non-logophiles). It can tell you tens of thousands of definitions and mark your page while it’s at it.
Young bookworms can hone their vocabulary as soon they learn how to read. The brightly-colored kids’ bookmark has bigger buttons that make it easy for little fingers to navigate and the definitions are taken directly from the Oxford Primary Dictionary.
Even grownups encounter words they don’t know. The adult version gives you access to 38,000 words definitions taken directly from the Collins English Dictionary. This way, when the plot thickens you’re not getting up (or distracted—especially by your phone).
Mark your page with a dictionary/bookmark and sharpen your vocab as the plot thickens.
