The verb is derived from the adjective 'unsicher' (insecure/uncertain). The prefix 'ver-' causes a change of state here, similar to 'verbessern' (to improve, literally to make better). 'Verunsichern' therefore literally means 'to make insecure'.

His critical question briefly unsettled me.
'Verunsichern' (to unsettle) is an inseparable verb because it begins with 'ver-'. The prefix remains firmly attached to the verb in all sentence forms and tenses.

This verb is transitive and always needs an accusative object. You always unsettle 'jemanden' (someone) or 'etwas' (something).

to confuse
'verwirren' and 'verunsichern' both describe that someone is no longer completely sure. 'verwirren' mainly means that information or situations confuse your mind. You no longer understand something clearly. 'verunsichern' focuses more strongly on the feeling: someone begins to doubt, becomes anxious, or loses self-confidence. The words can be confused because confusion often also causes uncertainty. As a guide: for complicated explanations or a lot of information, 'verwirren' fits. For criticism, doubt, or fear, 'verunsichern' is a better fit.
