When my husband and I are having problems doing something that we need to do, such as open a can when we've lost the can-opener! ... I say.... "Well, we'll have to do it SOMEHOW!" We look at the can, we scratch our heads, and we think. We try all sorts of things and all sorts of ways to open that can without a can-opener. With luck, we'll get it open SOMEHOW. That's just one example. I'm sure others will give you more examples, and a good explanation. It's a useful word.

Somehow he manages to get whatever he wants. I really wish that somehow I could afford a holiday in the Caribbean.

James somehow wants to know how he can use that word in a conversation.

"I will win somehow." I use it only in certain situations.
