Etymology
the word 'abnormality' is built upon the classical latin concept of a standard or rule, embodied in 'norma', which referred to a carpenter's square for measuring right angles. the prefix 'ab-' signifies a departure or deviation from this established standard. the suffix '-ality' consolidates the adjectival form 'abnormal' into an abstract noun, denoting the state or condition of being away from the norm. thus, the term's journey from a concrete tool for ensuring correctness to an abstract concept describing a deviation encapsulates a logical progression from physical measurement to societal and biological standards.
