smokeless

the word 'smokeless' is a modern english compound formed by combining the native english word 'smoke' with the adjective-forming suffix '-less'. the old english root 'smoca' is of germanic origin, likely related to the act of smoking or emitting vapor. the suffix '-lēas', also from old english, originally meant 'devoid of' or 'free from', and is cognate with the german '-los' and dutch '-loos'. the straightforward combination of these two elements creates a transparent meaning, directly signifying 'free from smoke' or 'without smoke', a concept that gained particular relevance with the development of cleaner combustion technologies and products.

Structure: smoke (noun/verb) + less (adjective suffix) smoke (from old english 'smoca', meaning smoke or fume; functions as the base noun/verb). less (from old english '-lēas', meaning devoid of, free from; functions as a suffix forming adjectives).
