Somehow means in a way that is not known, not explained, or not important to explain. It often shows surprise that something happened at all.
From Middle English *sumhowe*, combining *some* + *how*. It follows a common English pattern of forming adverbs like *anyhow* and *everyhow* (the latter mostly disappeared).
When people say “somehow I passed the test,” the word hides the messy details and jumps straight to the result. It’s a linguistic shortcut for “I can’t or don’t want to explain the process.”
