There’s some useful advice on a site I found today called Language Learning Tips. One of the tips for building vocabulary is that you try to learn three new words in the language(s) you’re studying every day, and that you write them down in a diary or blog. After a year, you’ll have a vocabulary of over a thousand words.
I think this technique could be expanded by trying to use the new words in sentences, and maybe even building up a story with them.
I tried to learn five new words a day in seven languages for several months with some success. Though I think maybe I was a bit overly ambitious. Maybe three words a day in five languages would be more achievable. The trouble is, which languages? Definitely Welsh, Irish and Spanish, and perhaps Japanese and Czech.
Have you used this technique or something similar?
