To a certain degree or extent; not completely or entirely.
The news was somewhat of a surprise.
Somewhat is formed from "some" (from Old English "sum", meaning a certain amount or number) and "-what" (from Old English "hwæt", meaning what or how much). The word "somewhat" refers to a certain amount or degree of something, indicating a moderate or limited extent.
Think of 'some' as a certain amount and '-what' as asking about how much — together, they help you remember that 'somewhat' means a certain degree or amount.
No commonly confused words.
