Questions & Answers about Wir haben die Luftschleuse deinetwegen geprüft.
Why use deinetwegen instead of just saying wegen dir?
deinetwegen is the standard, grammatically correct way to say "because of you" (singular informal). It is a special pronominal form made by combining the possessive base (dein), a connecting -et-, and wegen. While you will hear wegen dir (using the dative case) very often in everyday spoken German, deinetwegen is what you should use in writing and formal situations.
Could I put deinetwegen before die Luftschleuse?
Yes, you absolutely can! In fact, saying Wir haben deinetwegen die Luftschleuse geprüft follows the standard German word order rule where adverbial phrases (like a reason or cause) generally come before the direct accusative object (die Luftschleuse). Placing deinetwegen at the end of the sentence, as shown here, adds special emphasis to it—highlighting that we checked the airlock because of you specifically, rather than for some other reason.
What does the Schleuse part of Luftschleuse mean on its own?
A Schleuse is a lock (like a canal lock for boats), a sluice, or a floodgate. When combined with Luft (air), it becomes Luftschleuse ("airlock"), which is a compartment with two doors used to pass between areas of different pressure, such as on a submarine or spaceship.
