Sometime vs. Some Time vs. Sometimes
“Sometime” most often points to an unspecified time, “some time” refers to an amount or period of time, and “sometimes” means on some occasions. The spacing and final -s therefore mark different time concepts rather than interchangeable spellings.
Use “sometime” for an unspecified point of time, “some time” for an unspecified amount or period of time, and “sometimes” for frequency—on some occasions. Context matters more than a simple one-word/two-word slogan.

Quick tests
Meaning / construction test
Is the expression answering when, how much time, or how often?
If yes: When → “sometime”; duration/amount → “some time”; frequency → “sometimes.”
If no: Check whether “some” directly modifies the noun “time” in an ordinary noun phrase.
Caveat: This is a core-meaning diagnostic, not a substitute for parsing the sentence. “Some time” is a noun phrase; “sometime” and “sometimes” serve different adverbial functions.
Examples

“Sometime” points to an unspecified point of time.

“Some time” names an amount or duration of time.
