I randomly thought of it, how many words do you know, without that they are acronyms (example you can't write "DM" for "direct messages" but slang is allowed) for something, that are only 2 letters long in your mother-tongue. So for example if you would be french you should post as many french words with 2 letters as possible, if you get what I mean.
I go first and try with German
- an
- in
- zu
- tu
- ja
- ne
- nö
- ex
- wo
- ha
- Ah
- so
