I am big fan of a YouTube channel called Language Transfer. I have used it for Spanish, Arabic and Italian, and I would listen to an episode mostly every morning while getting dressed or at night while cooking. Language Transfer’s method for learning is termed the “Thinking Method” which means that you are remembering grammar and vocabulary not just by simply memorizing it but by understanding the logic behind it. It does so by transferring the knowledge you already have from other languages to your target language. Remembering, then, becomes a way of following a mental process of logic steps, which both makes it easier to trace things back if forgotten and provides you with a better understanding of the language. This works especially well between English and Latin languages, because you can ‘transfer’ a lot of words from one to the other (thanks to William the Conquerer).
Following a list of the most frequently used words in a language is a very efficient way to learn important vocabulary. This list also features example sentences for every word.
If you make an account on this website, you can opt for a great daily or weekly newsletter with new words and example sentences at your own level.
This is a silly but entertaining educational series available in a couple of languages, especially designed for language learners. It’s about a group of friends and their adolescent problems and attempts to find love. The difficulty of the dialogues (all subtitled) is increasing with every episode and it thus works great as a support to regular studying.
The daily news but in “easy” French (not really easy still, I must admit).
I never recommend Duolingo as a main source for starting a language as in my opinion it doesn’t focus enough on grammar, but for me it works wonderfully as a support to regular lessons and as a tool to keep in touch with the language when you’re not actively studying it.
Reading in another language is effective for learning but not much fun if you have to look up every other word. This application called Readlang is a great free addition to your browser that gives a translation simply by clicking on a word. Even better: it saves those words (and the sentence in which they appear) for later review as flashcards.
If you use Spotify, give my favorite French songs a try!
A last tip: if you already know another Latin language, the best thing you can do is buy a grammar book or vocabulary list in that language. Even when you have to single out the faux amis, this will save you a lot of time and efforts and makes language learning much more interesting.
