It's important to distinguish between:
* "Sometimes" (one word): This is an adverb meaning "occasionally" or "now and then." It's the correct spelling in most cases.
* "Some times" (two words): This is a phrase meaning "a few occasions" or "several instances." It's only used when referring to a specific number of times.
Here are some examples:
* Sometimes I go for a walk in the park. (Adverb, meaning "occasionally")
* I've been to the park some times this month. (Phrase, meaning "a few occasions")
Therefore, the word "sometimes" is rarely written as "some times" in literature. It's typically spelled as one word.
