Morphology

line + roulette

The compound is a straightforward noun+noun composition: 'line' modifies the technical noun 'roulette' (a curve traced by a point on a rolling figure), so the phrase denotes a roulette associated with a line or generated by a line. This compositional pattern is regular in English (and common cross-linguistically in technical terminology), so a learner who knows both constituents could infer the meaning.

Etymology

Line roulette comes from a simple rolling picture: imagine a shape with a marked point that rolls around another shape and the point draws a 'path' on the ground. The words line and roulette show this rolling idea, so line roulette means the 'curve' made when one shape rolls around another.
