What does guessable mean?
Guessable is an adjective describing something that can be guessed or inferred because it is sufficiently predictable, recognizable, or revealing. The word is especially common in discussions of passwords, riddles, hidden locations, patterns, and intended solutions. Saying that something is guessable does not always imply that the answer is completely obvious, but it indicates that a person could arrive at it through reasoning, familiarity, or the elimination of alternatives. A guessable password may satisfy the technical requirements of a system while still being easy for an attacker to deduce; a guessable answer may be intended to reward insight rather than obscure knowledge. The adjective is common in both British and American English and can carry a mildly critical connotation when applied to information that is supposed to be secure or concealed. Its usefulness lies in describing the balance between what is disclosed and what can reasonably be inferred.

Where does guessable come from?
Guessable was formed by combining the English verb guess with the suffix -able, which produces adjectives meaning “able to be” or “capable of being.” The base verb guess entered Middle English through guessen and ultimately derives from Old Norse geysa, meaning “to guess.” Related forms such as guesswork and guessworthy preserve the same root, while guessable specifically emphasizes that something can be determined by guessing.
