"As a figure of speech it has propriety and force only so far as it suggests that the emotion of the speaker is so great as to make him forget how he began his sentence" [Century Dictionary]. Related: Anacoluthic.
Anacoluthon, though a grammatical defect, is a rhetorical beauty, if naturally produced or imitated; as, "If thou art he--but oh ! how fallen!" "He who hath seen life in all its shapes, and fully knows its good and evil--No ! there is nothing on earth which can make a wise man desire a greater length of days than heaven appoints." These are instances in which the break down is the effect of emotion. [James R. Boyd, "Elements of English Composition," 1874]
anaconda (n.)
1768, a name first used in English to name a Ceylonese python, it was applied erroneously to a large South American boa, called in Brazil sucuriuba. The word is of uncertain origin, and no similar snake name is found now in Sinhalese or Tamil. One suggestion is that it is a Latinization of Sinhalese henacandaya "whip snake," literally "lightning-stem" [Barnhart]. Another suggestion is that it represents Tamil anaikkonda "having killed an elephant" [OED].

The tune is late 18c. and may be the work of society member and court musician John Stafford Smith (1750-1836).
