unheard
Not listened to or ignored when someone is speaking.
Unheard means not listened to or not given attention when speaking. When someone's voice goes unheard, others ignore or dismiss what they're saying, even if it's important. A student with a good idea might feel unheard if classmates talk over them during group work. A younger sibling might complain their concerns go unheard when older family members make all the decisions.
The word also means something never encountered or experienced before. An unheard-of discovery is so unusual or unprecedented that no one has seen anything like it. If your friend claims to have found an unheard-of species of butterfly in the backyard, they're saying it's completely new to science. When someone achieves an unheard-of victory, like winning a championship on their first try, it means the accomplishment is extraordinarily rare.
These meanings connect: both involve something not receiving recognition or acknowledgment. Whether it's a person's words being ignored or an achievement so rare it's never happened before, unheard describes an absence of attention or precedent.
