Do you speak another language or do you want to learn one?
There’s no better way to learn a language than through studying abroad. From Spanish, French, and Italian to Mandarin, Japanese, and Arabic, many programs are designed to improve your language skills-- no matter what your fluency level is.
Some programs are fully immersive (where you will only speak the host language), while others have no language requirement and include language courses as part of the overall curriculum.
If language-learning is among your main priorities for study abroad, you should probably select a program which is at least a month long and which incorporates opportunities for interaction with local people.
