Sense: adjective/1

All four words describe a lack of safety, but with different focuses. 'Vulnerable' is the broadest and most common term — it can describe physical, emotional, social, or systemic weakness, and does not imply total inability to defend (e.g. 'Children are vulnerable to online scams'). 'Helpless' emphasises a person's inability to act or change the situation by themselves, even if help is available nearby (e.g. 'She felt helpless watching the car slide on the ice'). 'Unprotected' is neutral and often temporary or even voluntary — it simply states that no protection exists (e.g. 'unprotected skin in strong sunlight'). 'Exposed' highlights being out in the open and directly reachable by danger (e.g. 'The soldiers were exposed on the open road'). 'Defenceless' is the strongest of the four — it implies a complete lack of any means of protection, whether weapons, strength, or allies, leaving a person, animal, or place open to attack without any way to fight back.

Etymology

LatinOld FrenchEnglish

Formed from the noun 'defence' (meaning protection against attack, from Old French 'defense', which came from Latin 'defensa', the feminine past participle of 'defendere' — to ward off or protect) plus the suffix '-less' (meaning 'without'). The word therefore literally means 'without defence'. The American spelling 'defenseless' uses a 'c'-less form of 'defence'.
