Questions & Answers about Es ist gut, wenn du dich im Fitnessstudio anmeldest.
Why is anmeldest written as one word at the end, instead of meldest an?
Because this is a subordinate clause starting with wenn (if). In a normal sentence, the separable prefix an would go to the very end (like Du meldest dich an). But in a subordinate clause, the conjugated verb is pushed to the end and reconnects with its prefix, forming the single word anmeldest.
Why is the word dich in this sentence?
The German verb for to sign up or register is sich anmelden, which is a reflexive verb. You are literally registering yourself, so you must use the accusative reflexive pronoun dich to match du.
Why do we use im here instead of just in?
The word im is a contraction of in and the dative article dem. We use the dative case here because it answers the question of where something happens (a fixed location at the gym). Since Fitnessstudio is a neuter noun (das Fitnessstudio), in dem shrinks down to im.
Can I change the order and put the wenn clause first?
