History and etymology of impregnable

The adjective 'impregnable' has its etymological roots in Latin, specifically from the Latin word 'impregnabilis.' This Latin term combines 'in,' meaning 'not,' and 'pugnabilis,' meaning 'able to be fought' or 'defended.' Thus, 'impregnabilis' conveyed the idea of something that cannot be easily fought or breached, making it exceptionally strong and secure. As it transitioned into English, 'impregnable' retained this fundamental meaning, describing something as highly resistant to conquest, breach, or being overcome. The etymology of 'impregnable' vividly illustrates the notion of an almost impenetrable defense, emphasizing the formidable nature of that which is exceptionally strong and secure against external threats or challenges.
