"I like long winter evenings."
Translation:Lubię długie zimowe wieczory.
I assume then that "długie" is in the accusative case as well? I am slowly picking up which verbs take which cases, one verb at a time. (Usually one verb per lesson. In about 20 years, give or take a decade, I may have them all finally listed, after which I might finally complete this tree/course.)
Well, -owy is a common ending for an adjective (and "zim-" is the stem), but it's not the only ending, for example the adjectives for spring/summer/autumn would be: "wiosenny/letni/jesienny". I don't know if there are clear rules for that. In case you're wondering why not "zimny" for "winter" then - it means "cold" ;)
