Soothsay is formed from "sooth" (from Old English *sōþ*, meaning truth) and "say" (from Old English *secgan*, meaning to speak). The word refers to the act of speaking the truth or predicting the future based on truth.
Think of 'truth' ('sooth') being 'spoken' ('say') — that's why soothsay means to speak the truth or predict the future.
