Easy, medium or a long project

The Foreign Service Institute sorts languages by the weeks of full-time class an English speaker needs to work in them. Closest to English means 24 to 30 weeks; Hardest for English speakers means 88. After your first press, the list beside the button narrows the draw to one of those groups or to a region.

What languages should I learn together?

Set the count to 3 and keep two that share a region, such as Spanish and Portuguese or Hindi and Urdu, which are close relatives: one makes the other easier.

Tips
  • A language spoken where you live, work or travel is easier to keep up, because you can use it every week.
