Learn Finnish: Emme halua tuhlata rahaa emmekä irtautua ryhmästä. - We do not want to waste money nor break away from the group.

In Finnish, you generally do not use ja (and) followed by a negative verb. Instead, you attach the enclitic -kä to the conjugated negative verb. Since the subject is 'we', the negative verb is emme, making it emmekä (and we do not / nor do we).

Why is the group in the elative case (ryhmästä)?

The verb irtautua means 'to break away' or 'to detach oneself'. Because the action involves moving away or separating from something, Finnish naturally requires a 'from' case, usually the elative (-sta/-stä).

Is the verb irtautua related to other words?

Yes, it is derived from the word irti, which means 'loose' or 'detached'. The -utua ending is a common suffix used to create reflexive verbs, so irtautua literally translates to 'to detach oneself'.

Why is raha in the partitive case (rahaa)?

There are two reasons that overlap here. First, negative sentences generally require a partitive object, though technically the main verb being negated here is halua (want). Second, even in an affirmative sentence, tuhlata (to waste) usually takes a partitive object when dealing with mass nouns like raha (money) because you are wasting an undefined amount of it, not a specific, closed total.
