Just a signpost to share my language learning experiments.

Currently working on my German and Russian, will resume Mandarin next year.

As for Dutch: depends- I have to complete updating the online translation of a grammar whose Acrobat version translated in Italian in 2009 (while living in Brussels), but otherwise, unless I will have missions requiring Dutch, my reading skills proved in 2015-2018 to be enough for my business activities (and I had not need to speak it).

Other languages: stay tuned, as I learned on short-term purposes a few in the past, and then dropped when not needed anymore, but would maybe have to make a comeback on some.E.g. once my Russian reaches B territory, I have a long-standing promise to my Latvian friends that I will resurrect my late 1990s Latvian

Incidentally: in order to leave the material online, for each "experiment" since 2009 I created a website on wordpress.com

More updates will be always published under the Language learning experiments menu option on the left.
