dare
This word carries a strong tension between internal courage and external pressure. When used as a personal attribute, it describes the psychological threshold of bravery required to face a risk. When used as a challenge, it shifts the focus to social competition or provocation, often implying a test of will or a desire to see someone succumb to peer pressure. Grammatically, this word is unique because it can function as a semi-modal verb. In negative sentences or questions, it often drops the to-infinitive (e.g., "I dare not go" instead of "I do not dare to go"), a property that distinguishes it from standard transitive verbs.
