IPA: /ˈsɛkəndər/
KK: /ˈsɛkəndər/
A person who supports or endorses a proposal or motion in a formal meeting, often in parliamentary settings.
During the meeting, John was the seconder for the motion to increase the budget.
**Seconder** → The word is derived from 'second' (from Latin *secundus*, meaning following or second) and '-er' (meaning a person who). A seconder is a person who supports or follows a motion or proposal.
Think of someone who is 'following' ('secundus') to support an idea — that's what a seconder does.
