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'.
