Etymology
The word 'mistrustful' is a layered construction built upon the core Germanic concept of 'trust'. The root 'trust' entered English from Old Norse 'traust', conveying firmness and confidence. The prefix 'mis-', of Germanic origin, was attached to indicate a negative or faulty condition, turning 'trust' into its opposite: a lack of confidence or suspicion. Finally, the Old English adjectival suffix '-ful' was added, transforming the state of 'mistrust' into a descriptive quality for a person who possesses or exhibits that feeling. Thus, the word logically assembles to mean 'characterized by having bad or incorrect confidence'.
