What does sinistrality mean?
Sinistrality means the condition or quality of being left-handed. It is a formal and comparatively uncommon noun, usually encountered in discussions of anatomy, psychology, anthropology, design, or the prevalence of different patterns of handedness. In ordinary conversation, people are more likely to say that someone is left-handed or to refer to left-handedness. The term can describe an individual characteristic, but it may also be used more generally when discussing the frequency of left-handedness in a population. Sinistrality comes from the Latin sinister, meaning “left,” and is closely related to the adjective sinistral, meaning “left-handed” or “relating to the left.” Although its vocabulary is specialized, the underlying idea is familiar: most people are right-handed, while a smaller proportion write, draw, or perform other tasks primarily with the left hand.
