odorless

the word 'odorless' is a modern english compound formed by combining the noun 'odor' with the suffix '-less'. 'odor' entered english via old french from the latin odor, which itself derives from the pie root h₃ed- meaning 'to smell'. the suffix '-less' originates from old english -lēas, meaning 'free from' or 'without', which is related to the verb lēosan meaning 'to lose'. the literal construction 'smell-without' transparently conveys the modern meaning of lacking any perceptible scent, a straightforward application of a productive english word-forming pattern to a classical root.

Structure: odor (smell) + less (without) odor (from latin odor meaning 'smell, scent'), less (from old english -lēas meaning 'devoid of, free from', an adjective-forming suffix)
