the word 'still' originates from the old english 'stille', meaning 'motionless, stationary, at rest, quiet'. this old english term is derived from the proto-germanic 'stillijaz', which itself is likely from the proto-indo-european root 'stel-', meaning 'to put, stand'. the core semantic connection is the concept of being placed or set, leading to a state of immobility or calm. from this foundational meaning of physical and auditory quietness, the word's meaning expanded metaphorically. the adverbial senses, such as 'even now' or 'nevertheless', developed from the idea of a continuous, unchanging state persisting over time or despite other circumstances.

the word 'still' is a simplex word of germanic origin. it cannot be meaningfully segmented into smaller morphemes within modern english spelling without resorting to reconstructed proto-forms.
