IPA: /ʌnˈhɪndəd/

Not stopped or prevented from doing something; free to act without obstacles.
She moved through the crowd unhindered by any distractions.
Unhindered → It is formed from "un-" (meaning not) and "hindered" (from Old English "hindrian", meaning to obstruct or impede). The word "unhindered" means not obstructed or impeded, allowing free movement or action.
Think of being 'not' ('un-') 'obstructed' ('hindrian') — that's why unhindered means free to move or act without obstacles.
