Etymology

PIE word *úd From Middle English utmost, utemest [and other forms], from Old English ūtmest, ūtemest [and other forms], from ūt, ūte (“out; outdoors, outside”) + -mest (suffix meaning ‘furthest’, used to form superlatives of some adjectives) (and conflated with most). Ūt is derived from Proto-Germanic ūt (“out, outward”), from Proto-Indo-European úd (“out, outward”). Equivalent to out + -most.
