Not giving support or confidence; discouraging.
The teacher's comments were unencouraging, making the students feel less motivated.
Unencouraging → It is formed from "un-" (meaning not) and "encourage" (from Old French *encourager*, meaning to inspire with courage). The word "unencouraging" means not inspiring courage or confidence.
Think of 'not' ('un-') inspiring someone with 'courage' — that's why unencouraging means lacking encouragement.
