The best language learning system I’ve ever used is called Language Transfer, and it’s completely free (supported by donations).

It focuses on getting you to use constructs and patterns that you already know in your own language and transferring those to the new language. That way you start off with a good vocabulary and basic grammar.

They have Spanish, as well as German, French, Greek, Turkish, Arabic, Swahili.

There is also an app, which is plain but extremely usable.

My uncle was sent from Canada to South Korea in 1983, to help with their CANDU nuclear reactors.

He flew on Korean airlines flight 007, a week before that same flight was shot down by the Soviet Union.
