Morphology

chromosomal + anomaly

The phrase 'chromosomal anomaly' is directly compositional: 'chromosomal' means relating to chromosomes and 'anomaly' means an unusual occurrence, so a learner who knows both words can infer it refers to an unusuality affecting chromosomes. While specific medical details (changes in number or structure and health consequences) are technical, the core meaning is transparent and predictable from the constituents.

Etymology

Chromosomal anomaly uses a simple picture: think of chromosomes as pages in the body's instruction book—chromosomal means about the chromosomes and anomaly means an 'unusual' or 'not normal' 'change'. If a page is missing, extra, or damaged, the instructions change, so the phrase means a 'change' in chromosome number or shape that can cause health problems.
