I love Finnish. Until I can think in Finnish, I will have to stand tall and on my toes to get even the most simple things right. Yes: I had this one wrong too! :-)
So if "vanhassa" means "in old", then "metsässä" itself means just the same, "in forest". Do I understand well then that if there comes any other adjective then it also gets "ssa" at the end? So for example "autossa, vanhassa, isoassa metsässä"? As for "in a strange, old, big forrest"?
Yes, although it feels a bit odd to have so many adjectives in a row. The most natural order is "oudossa, isossa, vanhassa metsässä".
If you have an adjective that reveals a personal opinion, that adjective usually comes first (like "outo" here). That's followed by the more neutrally descriptive adjectives: shape/size (iso), age (vanha), colour (valkoinen), origin (suomalainen), matter (puinen = wooden) and finally the noun. This order is not absolute though, as shorter adjectives tend to come before longer ones, and the more simple, everyday adjectives before complex ones.
In English, a sentence like "The bears are walking" can be broken into three parts. The subject: 'the bears'. The verb: 'are'. And an adjective (participle): 'walking'.
In Finnish, the verb and participle get combined into one word: kävelevät. By itself, kävelevät is a verb meaning 'are walking'.
Exactly one verb is needed, not two. Using two verbs, as in Karhut ovat kävelevät, would end up sounding like "The bears are are walking".
