✦Grammar Breakdown
Wiestellstdusicher,dassduesverstandenhast?
Wie (question word)
‘Wie’ introduces a ‘how’ question and is placed at the beginning of the sentence.
stellst ... sicher (verb phrase)
‘sicherstellen’ is a separable verb; in a main clause the prefix ‘sicher’ moves to the end, but here it stays attached to the verb as a fixed phrase ‘stellst ... sicher’.
dass‑clause (subordinate clause)
‘dass’ introduces a subordinate clause, which pushes the finite verb to the end (here ‘hast’).
Perfekt of verstehen
‘verstehen’ in perfect tense is formed with ‘haben’ + past participle ‘verstanden’.
Word order in questions
In a yes/no question the verb comes directly after the question word; in this ‘Wie stellst du …?’ the verb ‘stellst’ follows ‘Wie’.

✕Common Mistakes
Wie sicherst du dich, dass du es verstanden hast?
‘sichern’ is not used reflexively here; the correct construction is ‘stellst du sicher’.
Wie stellst du sicher dass du es verstanden hast?
Missing comma before the subordinate clause; German punctuation requires a comma before ‘dass’.
Wie stellst du sicher, dass du es verstehst?
‘verstehst’ is present tense; the original phrase asks about a completed understanding, so the perfect ‘verstanden hast’ is needed.

Cultural Tip
German communication values clarity and precision. Asking ‘Wie stellst du sicher…?’ shows that you care about thorough understanding rather than just a quick acknowledgment. In formal settings you would replace ‘du’ with ‘Sie’: ‘Wie stellen Sie sicher, dass Sie es verstanden haben?’
