Many volunteers work in uncompensated roles to help their communities.
Uncompensated → It is formed from "un-" (meaning not) and "compensate" (from Latin "compensare", meaning to weigh together or to balance). The word "uncompensated" means not balanced or not compensated for something, indicating a lack of recompense or payment.
Think of 'not' ('un-') balancing or 'weighing together' ('compensate') — that's why uncompensated means something that hasn't been balanced or paid for.
