How can I learn words? By using them several times in various ways!!!
Reading and listening is crucial. When you read something and when you listen to something, review the words you understood by making a summary (writing or speaking). After looking up the words you didn't know, do the same! Some follow-up could be to repeat aloud language in those texts to get fluency and be correct, like we do at the TP section Useful Language!
Say aloud every now and then words you learned during the week, while you wait for the bus, in the bathroom, while you do the washing up, to get to sleep...
