Etymology
Etymology Information

'undefended' originates from English, specifically formed from the prefix 'un-' and the word 'defended', where 'un-' meant 'not' and 'defend' derives from Latin 'defendere' meaning 'to ward off or repel'.

Historical Evolution

'defendere' (Latin) passed into Old French as 'defendre' and into Middle English as 'defenden/defend'; the negative prefix 'un-' was attached in English to form 'undefended' (modern English formation).

Meaning Changes

Initially related to the literal sense of 'not warded off' or 'not defended against attack'; over time it became the general adjective meaning 'lacking protection' or 'exposed'.
