German grammar (see German Grammar) has two major systems — cases and word order — that benefit enormously from a deliberate learning sequence.
These two cases cover subject and direct object, enough for real sentences — introduce dative (tied to specific common verbs first) and genitive later, as vocabulary and sentence complexity grow.
Deliberately practice sentences that start with a time expression or object rather than the subject, to internalize that the verb stays in second position regardless — this habit needs active practice, not just passive understanding.
Once verb-second in main clauses feels automatic, practice subordinate clauses (introduced by "because," "that") where the verb moves to the end — treating this as a distinct rule to learn, not an extension of verb-second.
Since separable prefixes interact directly with word order (the prefix moves to the end of the clause), they're easier to learn once the underlying word-order rules are already comfortable.

Nominative and accusative — they cover the subject and direct object, enough for real sentences, with dative and genitive worth adding progressively afterward.
Deliberately practice sentences that start with something other than the subject (like a time expression) — this active practice, not just understanding the rule, is what makes it automatic.
No — subordinate clauses (introduced by words like "because" or "that") push the verb to the end, a distinct rule from main-clause verb-second order, worth learning separately.
After basic word order feels solid — since separable prefixes interact directly with sentence structure, they're easier to learn once the underlying word-order rules are already comfortable.
