Which of the following is an antonym of the word “Confident”?

Answer: diffident (spelled d-i-f-f-i-d-e-n-t)

Meaning: lacking confidence; shy, reserved, or hesitant to assert oneself.

• Why this is the antonym: "confident" describes someone who has self-assurance; "diffident" describes someone who lacks self-assurance.

• Why the other choices are wrong: "Confidant" is a noun meaning a trusted friend or adviser (not an adjective). The other choices are misspellings of the correct word.

• Spelling tip: remember the form "dif-fid-ent" with double f (diffident) and the suffix "-dent".
