I am enjoying the learning platform of Coursera.org.. there is a catalogue of showcase courses from international universities... I am already studying on a few of them.... But was delighted to find this course.... as I love languages....have been fascinated by how they develop and how we communicate to one another.
Miracles of Human Language an introduction to Linguistics... run by Leiden University and Meertens Institute - the course is free but you can purchase a certificate...

Also check the Ethnologue on all the world languages.... origins and where spoken... https://www.ethnologue.com/ fascinating tool and data resource.
