The days of having a dictionary on your bookshelf are numbered. But that’s OK, because everyone already walks around with a dictionary – not the one on your phone, but the one in your head.
Just like a physical dictionary, your mental dictionary contains information about words. This includes the letters, sounds and meaning, or semantics, of words, as well as information about parts of speech and how you can fit words together to form grammatical sentences. Your mental dictionary is also like a thesaurus. It can help you connect words and see how they might be similar in meaning, sound or spelling.
As a researcher who studies word retrieval, or how you quickly and accurately pull words out of your memory to communicate, I’m intrigued by how words are organized in our mental dictionaries. Everyone’s mental dictionary is a little bit different. And I’m even more intrigued by how we can restore the content of our mental dictionaries or improve our use of them, particularly for those who have language disorders.
