| Definition: | an ungrammatical construction in which two or more independent clauses are improperly joined without a conjunction or appropriate punctuation |
| a chattering or flighty, light-headed person. |
| a fool or simpleton; ninny. |
A grammatically faulty sentence in which two or more main or independent clauses are joined without a word to connect them or a punctuation mark to separate them: “The fog was thick he could not find his way home.” The error can be corrected by adding a conjunction with a comma (“The fog was thick, and he could not find his way home”) or by separating the two clauses with a semicolon (“The fog was thick; he could not find his way home”).
