anti-sway bar singular

Morphology

anti-sway + bar

The compound is built from familiar pieces: 'anti-' (against) + 'sway' (to move side-to-side) + 'bar' (a rigid rod), so the meaning 'a rod that counteracts sway' is directly derivable from the constituents. Although it's technical automotive vocabulary, the morphemes and construction are transparent and cross-linguistically regular (cf. 'anti-roll bar'), so a B1 learner who knows the parts would likely understand it.

Etymology

Anti-sway bar gets its name from its parts: anti meaning 'against', sway meaning 'side-to-side movement', and bar meaning a metal rod. Imagine a metal rod that connects a car's wheels and stops it from leaning in turns, so the name means 'a rod that keeps the car steady'.
