Listed below are the links to free online visual dictionaries.  Visual dictionaries use images rather than blocks of text to define words. When you type in a word, the platform will pull up webs of related words and indicate how each word should be used (like as a noun, a verb, an adverb, etc.) based on the color of the lines.  You can hover your mouse over any word and a quick, one-sentence definition pops-up. You can also move and manipulate the web by dragging words around. It’s a great way to make abstract concepts more concrete and visible. Kinesthetic learners might enjoy manipulating the webs. It’s also a good way to learn new words by seeing the words that are associated  with the new word, and the webs do a great job at illustrating how the words are related.
