IPA: /nɒnˈstɑːtə/
KK: /nɑnˈstɑrtər/
A person, idea, or plan that is unlikely to succeed or be accepted.
The proposal was considered a nonstarter due to its high costs.
Nonstarter → It is formed from "non-" (meaning not) and "starter" (from the verb "start", meaning to begin). The word "nonstarter" refers to something that does not begin or is not viable, often used in contexts where an idea or plan fails to gain traction.
Think of 'not' ('non-') being combined with 'beginning' ('starter') — a nonstarter is something that doesn't get off the ground.
