Etymology
the verb 'sidle' emerged in the late 17th century as a back-formation from the now-archaic adverb 'sideling,' which meant 'sidelong' or 'sideways.' 'Sideling' itself originated from the old english word 'sīd,' meaning 'extensive' or 'broad,' which evolved into the modern noun 'side.' the core logic of the word's formation is the conversion of a directional concept—moving laterally—into a specific, often furtive, manner of movement. this etymological journey illustrates how a simple spatial term ('side') can, through grammatical conversion and semantic narrowing, give rise to a verb describing a cautious, indirect, and typically sideways approach.
Analysis
this word is a simplex form derived from the obsolete adverb 'sideling,' meaning 'sideways.' it is not productively formed from separable modern english morphemes.
