Questions & Answers about Vartija on aina mukana.
This lesson is about the comitative case (-ine). Why isn't it used in this sentence?
The comitative case (which would look like vartijoineen) is quite formal and almost always used in the plural. In everyday Finnish, it is much more natural to express the idea of being 'with' or 'along' by using the adverb mukana, which is why it is shown here as a practical alternative.
Why use mukana here instead of kanssa?
Kanssa usually needs to follow a specific noun in the genitive case, like vartijan kanssa (with the guard). Mukana works perfectly on its own as an adverb meaning 'along' or 'involved' without needing to explicitly state who the guard is accompanying.
What is the grammatical makeup of the word mukana?
It is actually the essive case (which ends in -na) of an old base word muka. The essive case indicates a state or role, so mukana literally means being in a state of accompaniment. You will also see this root in directional words like mukaan (moving into accompaniment).
Why is the word order Vartija on aina mukana rather than Mukana on aina vartija?
The current word order translates to 'The guard is always along', treating the guard as a known, specific subject. If you flipped it to Mukana on aina vartija, it would become an existential sentence meaning 'There is always a guard along', which introduces an unknown or generic guard.
