Usage tips
Word structure
The adjective is made up of 'die Wehr' (defense) and the ending '-los', which means 'without'. 'Wehrlos' (defenseless) therefore literally means 'without defense'.
EXAMPLE
Ohne seine Waffen fühlte sich der Soldat völlig wehrlos.
Without his weapons, the soldier felt completely defenseless.
Sentence structure and use
'Wehrlos' (defenseless) is often used in the fixed expression 'jemandem/etwas wehrlos ausgeliefert sein' (to be defenselessly at the mercy of someone/something). The threat is in the dative. Alternatively, you can use 'gegen + accusative' (against + accusative).
EXAMPLE
Die Bevölkerung war der Willkür des Diktators wehrlos ausgeliefert.

wehrlos vs hilflos
helpless
'hilflos' and 'wehrlos' both describe that someone can do little in a difficult situation. 'hilflos' is more general: someone needs help, does not know what to do, or cannot help themselves. 'wehrlos' is more specific and fits when someone cannot defend themselves against an attack, pressure, or a danger. Learners may confuse the words because a defenseless person often also seems helpless. When the focus is on a lack of help or not knowing what to do, you are more likely to say 'hilflos'. When it is about defense against something threatening, you say 'wehrlos'.
