I know you can't learn a language in three weeks, but let's see how I fail.
How much can I learn before my granny from Ethiopia visits?
I'm unemployed so I have time to study and I'm pretty motivated. You can often get from 0 to A1 level in a language within 100 hours of study.
I should be able to learn the writing system (it's a hard one), more than 100 words, and some amount of grammar.
Day Two: I get the general logic of verbs (mark subject with both prefix+suffix, except in the past tense where it's all suffix). I get the sentence structure (VSO). I'm working on memorising 1) the most common verb roots, 2) those prefixes and suffixes, 3) the written characters
Goal: if I can memorise 1) the verb prefixes+suffixes for the past+present+future, 2) a few hundred bits of vocab, 3) the writing system.... that'd be amazing... then I could string together basic sentences
