A subordinate clause (der Nebensatz) can't stand alone — and unlike the conjunctions you just learned, the words that introduce it (weil, dass, wenn) DO change the word order: the conjugated verb jumps to the very end of its clause.
Types you should know
weil
because
dass
that
wenn
if / when, repeated events

Subordinate clause → verb goes to the end.
Main clause
Subordinate clause
Ich bleibe zu Hause,
weil ich krank bin.
Ich glaube,
dass er Recht hat.
Ich rufe dich an,
wenn ich Zeit habe.
Memory trick: Main clause = normal word order. Subordinate clause = verb runs to the end, like it's chasing the full stop.
⚠ Common mistake: Don't leave the verb in position 2 after weil/dass/wenn — "weil ich bin krank" is wrong; it must be "weil ich krank bin".
