German
German punishes hesitation in a very particular way: the structure of your sentence has to be decided before you start saying it. That is a speaking problem, and no amount of reading solves it.

Barkley — I'll keep you talking, not reading.
To speak German comfortably you have to practice cases, verb position and separable verbs at conversational speed, and that only happens by speaking. Short daily sessions where someone corrects you as you talk build it faster than grammar drills. Lumen Speak is an AI tutor you can speak German with whenever you like.
Nominative, accusative, dative and genitive are manageable on paper. In speech you have to pick the right article and ending while also thinking about what you actually want to say. Only speaking builds that.
In subordinate clauses the verb lands last, so you must hold it in memory while producing everything else. Learners who have only read German routinely stall halfway through their first long sentence.
The prefix detaches and travels to the end of the clause. Forgetting to land it is one of the most common spoken mistakes, and it is almost invisible when reading.
Der, die and das are not decoration — they drive adjective endings and case forms. Producing them out loud, and being corrected, is what moves them from a list into a reflex.
Your speaking time is the point. The tutor keeps its own turns short so the session is not a lecture.
Corrections identify the specific broken phrase and the rule behind it in one line, in your language, so review afterwards is fast.
Difficulty moves in single steps, so you are stretched into longer clauses only once the shorter ones are reliable.
Your first session takes five minutes and starts with a short spoken check, so the plan fits where you actually are.
