Viele junge leute vs Viele junge I have been confused for the past few days, "Viele junge leute" means many young people, and "junge" is an adjective that why we added the "e" at the end, but why the "e" in "Viele", if you have more than one adjective shouldn't the "e" be added to the last adjective only. for example "Das ist eine grün, rot, schwarze CD", so why is it "Viele junge leute" not "Viel junge leute".
