Youtube is a good place to start learning new words, because you can see the pictures and hear the words as well as reading the word. This means that you get used to matching the sounds and spellings of French.
When you have learned new words, it can be fun to visit a French website and see how much you can work out.
This one is a clothing website. You can have a browse and choose a new wardrobe.
Songs are another great way of practising the language that you have learned.
Quizlet is a great way of learning the spelling of words and of hearing the words pronounced. You can practise at home.
There are lots of online lessons on the BBC website. This is a link to one about clothes.
