German - red.
Rot, rote, roter, rotes, - all denote the word "red," - can anyone give me a clear undestanding of exactly under which circumstances each one is used? Thanks....
In German, adjectives like "rot" (which is the basic form) need to be in grammatical agreement with the substantive (noun) they describe. That means you need to adjust for both gender of the noun (male/female/neuter) and its grammatical case (nominative, genitive, accusative, dative). This is one of the fundamental concepts in German and many other languages, and you'll just have to practise. Good luck :)
