IPA: /ˌʌnəˈbjuːzd/
KK: /ʌnəˈbjuːzd/
Not having been harmed or mistreated, especially in a physical or emotional way.
The child was happy and healthy, showing signs of being unabused.
Unabused → It is formed from "un-" (meaning not) and "abuse" (from Latin "abusus", meaning misuse or wrong use). The word "unabused" means not having been misused or wronged.
Think of 'not' ('un-') having been 'misused' ('abuse') — that's why unabused means not having been misused.
