What does sussed mean?
Sussed is an informal verb with two closely related meanings. It can mean to suspect someone of wrongdoing, deception, or dishonest intentions: “The neighbours suspected that something was wrong.” More commonly in the expression “suss out,” it means to discover or work out what is really happening, often through careful observation or investigation: “She sussed out the trick immediately.” The word has a brisk, conversational tone and is generally more common in speech than in formal writing. It is used in both British and American English, though its association with British informal usage remains noticeable. Because sussed can refer either to forming a suspicion or to uncovering the truth, its intended sense often depends on the surrounding phrase. In formal prose, suspect, suspecting, investigate, deduce, or discover will usually be clearer and more appropriate.
