History and etymology of deleterious

The adjective 'deleterious' has its roots in Latin, originating from the word 'deleterius,' which means 'harmful' or 'noxious.' This Latin term is derived from 'deletere,' a verb meaning 'to harm' or 'to injure.' The word 'deletere' is thought to be related to 'de-' (meaning 'away from') and 'lētum' (meaning 'death' or 'destruction'). Consequently, 'deleterious' entered the English language with its Latin sense intact, describing anything that has a harmful or damaging effect on something or someone. Its etymology emphasizes the notion of causing harm or injury, making it a suitable term for expressing the adverse consequences of various factors or actions.
