Morphology

chromosomal + aberration

The compound meaning is directly compositional: 'chromosomal' specifies the locus (chromosomes) and 'aberration' means an abnormality, so the phrase denotes an abnormality of chromosomes. This mapping is literal, follows normal English noun-modifier composition, and has clear parallels in other languages, so learners who know both constituents can infer the full meaning.

Etymology

Chromosomal aberration links chromosomal (from 'chromosome', a small 'colored body' seen inside a cell) and aberration (a word for something that 'goes away from the usual'). Picture a chromosome moving away from its normal place or changing shape, so the term means 'a change in the normal number or shape of chromosomes'.
