Definition= Memrise is a website that teaches multiple languages.
Why should I use memrise?=Memrise helps you to memorise vocabulary. Memorizing vocabulary helps you to become fluent in you language.
How do I get to memrise?= go to... www.memrise.com
Be careful because some of the people creating courses on Memrise are students.
There is one course that contained an error in its title, so I decided not to consider that course.
It is really useful, but definitely to use along with other stuff as on its own it doesn't help at all with grammar etc :)
I think memrise is pretty useful, but no substitute for DL. In Italian, for example, it seems very basic at first, but a bit later on, it does present phrases in a different way to DL, which is a good thing. You need as many sources as you can. Films, Radio, Literature etc and to saturate yourself in the stuff. But still, most of my learning has come from DL. Without DL I don't think I'd still be working at it now, after a year.
What is great about Memrise, is all the other stuff on there. I'm learning some history, botany and all sorts of things. But Khan Academy is the place to go for serious learning, e.g science and maths etc. But nothing comes close to DL when it's to do with language learning. :)
