Memrise is a language learning site/app that quickly teaches you vocabulary by associating words with images, cartoons, sayings, and more.
Pro Helps grow your vocabulary quickly
Memrise uses "mems" to increase your vocabulary, which are a way to connect a word to its meaning.
A common example is associating a word with an image.
Mnemonics are another one they use to help you remember new words. For example,
"le parcours" (route or course) could be remembered with the mem "People who do parkour pick their own route".
