The word "smokeless" is formed by combining the root word "smoke" with the suffix "-less".
The term "smoke" originated from Old English, where it was spelled "smoc". It derived from the Proto-Germanic word "smukkaz", meaning "smoke" or "dust". This Proto-Germanic word is believed to have its roots in the Proto-Indo-European base "*smeug-", which meant "to smoke" or "to emit smoke".
The suffix "-less" comes from Old English as well, where it was spelled "-leas". It indicates the absence or lack of something. In the case of "smokeless", it signifies the absence of smoke.
Therefore, the word "smokeless" emerged from the combination of the Old English word "smoc" (smoke) with the Old English suffix "-leas" (without).
