"Anyhow" is used in the same way as nevertheless. "I don't know why he didn't come, anyhow, we got by without him." "Anyhow" can also mean "in any way". "They came to the game anyhow they could." "Somehow" is use in the sense of "in some way" - we usually don't know what way exactly. "I don't know exactly how, but we have to finish this project somehow by Friday." "Somewhat" is used in the sense of "more or less" or "a little" "It's somewhat cold in here. Could somebody turn the heat up?"
