IPA: /rɪˈsɪndər/
KK: /rɪˈsɪndər/
A person or thing that cancels or revokes something, such as a law or agreement.
The rescinder of the contract made sure all parties were informed of the changes.
Rescinder is formed from "re-" (meaning again) and "scindere" (meaning to cut). The word means to cut again or to revoke something that was previously established.
Think of 'cutting again' when you hear 'rescinder' — it helps you remember that it means to revoke or take back something.
