## AI Etymology
gullible comes from gull ('to deceive, dupe') + -ible, an alteration of the earlier gullable, formed in the early 19th century. Morphologically, the ending is part of the etymology: the suffix is attached to the older base named in the history, producing a later English derivative. In present English, the adjective sense is "easily deceived or tricked", so the historical development ends in a clearly identifiable modern dictionary use. The same base also appears in related forms such as gull, and in derivatives such as gullibility and gullibly. Its semantic neighborhood includes credulous, naive, trusting, and unwary, which helps locate the modern sense without adding a separate etymological claim.
