Not willing to trust others or believe in their honesty.

Untrusting → It is formed from "un-" (meaning not) and "trust" (from Old Norse "traust", meaning confidence or reliance) and "-ing" (a suffix used to form adjectives or nouns). The word "untrusting" means not having confidence or reliance in someone or something.
Think of 'not' ('un-') having 'confidence' ('trust') in someone — that's what untrusting means.
