Although things seem difficult now, somehow we’ll be all right.
I know it's raining and there are a lot of rocks, but somehow we’ll hike the entire trail.
"Somehow or other" is a way to say somehow when you really want to emphasize that you don't know how something will happen. For example: "I haven't started writing my English paper and it is due tomorrow at 9am, but somehow or other I will find a way to finish it."
Somehowis normally used in conversation or other informal contexts and can help speakers emphasize that they don't know the way something happened. For example: "Even though Mary never answered any questions correctly in class, somehow she got a perfect score on the final exam. Maybe she cheated!"
