I can see your writing sucks. Well, maybe not yours, but someone's. And I can tell by the writer's improper use of one or two words.
For instance, the two-word phrase, "some day," consists of an adjective ("some") and a noun ("day") and refers to a single SPECIFIC day in the future.

"Someday," on the other hand, is a single-word adverb that refers to future events that will occur on a single day that is still indefinite or unknown in time.
