SMUG'GLE, v.t. [Sw. smyga; D. smokkelen, which seems to be allied to smuig, under hand; smuigen, to eat in secret; G. schmuggeln; Dan. smug, clandestinely. We probably have the root mug, in hugger mugger.]

1. To import or export secretly goods which are forbidden by the government to be imported or exported; or secretly to import or export dutiable goods without paying the duties imposed by law; to run.
2. To convey clandestinely.
