- Watch their news media. For instance, if you are learning Arabic, then watch Arabic media. It might be tough at first, but just go at it. Be a baby. Babies bombard their minds with input and eventually patterns form.
- Pick a TV show you saw and watch the whole thing again using language-you-want-to-learn subtitles. This can be fun, and well things will be mentioned so often they will stick. This is extremely effective, and my English vocabulary improved dramatically this way. I prefer this to carrying cards and trying to memorize them. Its unnatural.
- Go to a country that speaks it.
