In conversation how does one distinguish "Kosmos" from "Cosmos"

Everytime I am talking I am forced into distinguishing by saying "Kosmos with a K."  This is especially true if one is involved in a conversation where one must go back and forth between Kosmos and Cosmos.

Since the distinction in the two words is conceptually huge shouldn't the words be more distinct from each other?

Forgive me if this sound's like a Newbie's question, but I am new!
