Learn Swedish: Vi måste skrota tramset, det är inte alls genomförbart. - We must scrap the nonsense, it is not at all feasible.

In this sentence, inte alls acts as a fixed unit meaning "not at all". It usually stays together directly after the verb in a main clause. While you might occasionally see alls inte in older or highly formal texts, inte alls is the natural word order for modern Swedish.

How is the adjective genomförbart constructed?

It is built from the verb att genomföra, which means "to carry out" or "to implement" (literally "through-lead"). Adding the suffix -bar makes it an adjective meaning "doable" or "feasible". Finally, the -t is added so it agrees with the neuter pronoun det.

Does trams just mean "nonsense", or is there a specific nuance to it?

Trams refers to silly, frivolous, or unserious behavior. While words like strunt or skitsnack might mean "rubbish" or "bullshit", trams specifically implies that something is childish, annoying, or a waste of time. The -et ending gives us the definite form "the nonsense".

Is skrota used figuratively here, just like "scrap" in English?

Yes! Just like in English, att skrota literally means to scrap a physical object at a junkyard (en skrot). Figuratively, as used in this sentence, it means to completely discard a bad idea, plan, or project.
