Which word means a plan that is not fully formed?

• A. ingenious
• B. inundate
• C. insipid
• D. inchoate

Answer: (D)

Understanding how a plan develops helps you pick the right word. The best fit is inchoate, which means something that is just begun and not yet fully formed or developed. It describes ideas, plans, or movements that exist in a rough, incomplete form with details missing. For example, a business plan that exists as rough notes and broad intentions but lacks specifics is inchoate.

The other options don’t convey this sense of being at an early, incomplete stage: ingenious means cleverly inventive, focusing on cleverness rather than the state of development; inundate means to flood or overwhelm; insipid means dull or lacking flavor or interest.
