The IPA phonetic transcription for "still" is /stɪl/ and for "less" is /lɛs/. The word "still" refers to something that remains the same or is continuous. Meanwhile, "less" denotes a decrease or a smaller amount. Together, these words create a comparative phrase that emphasizes the degree of unlikelihood or impossibility of something.
The phrase "still less" is an idiomatic expression that is used to introduce a further point or idea that is even more unlikely, contradictory, or absent than the one previously mentioned. It serves as a means to emphasize the increasing unlikelihood or inapplicability of something.
The term "still" here functions as an adverb that denotes continuing or even greater degree, and "less" serves as a comparative adjective indicating a smaller extent or amount. When combined, they intensify the negative or contrary nature of the previous assertion.
For instance, if someone were to claim that a certain course was challenging, they might proceed to expand by stating, "The advanced course was difficult enough for seasoned professionals, and still less suitable for beginners." In this context, "still less" implies that while the course may be challenging for the first group mentioned, it is even more inappropriate or difficult for the second group.
In summary, "still less" is an idiomatic phrase employed to emphasize a subsequent notion that is even more unlikely or unsuitable compared to the preceding one. It amplifies the negative or contrary argument being made, usually highlighting the unattainability or nonexistence of something.
The term "still less" originates from the combination of two separate words: "still" and "less". Each of these words has its own etymology:
1. "Still": The word "still" has its roots in the Old English word "stille", which means "motionless" or "quiet". In Middle English, it evolved to signify "constant" or "unchanging". The word ultimately derives from the Proto-Germanic word "stillijan", which means "to calm" or "to make quiet".
2. "Less": The word "less" can be traced back to the Old English word "lǣssa", which means "smaller" or "less". This word has common roots with other Germanic languages, such as the Old High German word "laz", meaning "less".
