Hook, line, and sinker means completely and without doubt or reservation; to be completely tricked or believe a lie or deception.
This idiom is often used in the forms swallow something hook, line, and sinker or fall for something hook, line, or sinker, but many other variations are possible, such as:
- Buy/bought it hook, line, and sinker
- Go/went for it hook, line, and sinker
Origin of “Hook, Line, and Sinker”
This idiom refers to fishing, in which a baited hook is attached to the end of a fishing line, and a leaded weight (sinker) is attached some distance further up the line. The allusion is to a hungry fish swallowing not only the baited hook but the sinker and line in between, as well; something extremely rare. The expression was first recorded in 1865.
Spelling and Common Misconceptions
Because “hook, line, and sinker” is usually spoken quickly in conversation, listeners frequently mishear or miswrite the expression as a single compound word or altered phrase:
- “Hookline and Sinker” (Incorrect): “Hook line” is often miswritten as a single compound word (hookline). However, the phrase consists of three distinct fishing tools separated by commas: the hook, the line, and the sinker.
- “Hooked, Lined, and Sinkered” (Incorrect): Adding past-tense -ed suffixes to every word (or turning “sinker” into a verb) is a common grammatical error. The correct idiomatic form uses the simple noun series preceded by a verb, such as “fell for it hook, line, and sinker” or “bought it hook, line, and sinker.”
- “Hook, Sink, and Liner” (Incorrect Spoonerism): A frequent verbal slip (spoonerism) rearranges the elements into “hook, sink, and liner” or “hook, line, and sink.” In proper English usage, the three-part sequence always remains hook, line, and sinker.
