IPA: /ɪˈvɪn.sə.bəl/
KK: /ɪˈvɪnsəbl/
Able to be shown or proven clearly; something that can be demonstrated or made evident.
The scientist presented evincible evidence to support her theory.
Evincible is formed from "e-" (meaning out of or from) and "vincere" (meaning to conquer or overcome). The word describes something that can be overcome or conquered, hence evincible refers to something that is not invincible and can be defeated.
Think of something that can be 'overcome' ('vincere') and is 'from' ('e-') a state of being strong. This helps you remember that evincible means something that can be conquered.
