Surface Forms

acid halide singular
acid halides plural

Morphology

acid + halide

The term is directly compositional: combining 'acid' (an acidic compound) with 'halide' (a halogen-containing compound) signals a halogen-containing derivative of an acid, so a learner who knows both constituents can infer the general meaning. The precise structural notation (–COX) and mechanistic details are technical chemistry knowledge beyond B1, but the basic semantic relation is transparently derived from the parts.

Etymology

Acid halide is a chemical name made from acid + halide. A 'halide' is a group with a halogen like chlorine or bromine that replaces the acid's usual 'OH' part, so the name literally tells you it is an acid changed by a halogen.
