* "Lickety": This part is likely derived from the sound of something moving quickly, like the rapid lapping of a tongue.
* "Split": This part could refer to the quick and sudden separation of something, like splitting wood.
Therefore, "lickety-split" likely describes something moving with the speed and force of a tongue lapping up something, or the sudden separation of something.
Possible Origins:
* Folk Etymology: It may have emerged from a combination of existing words that became associated with speed.
* Onomatopoeia: The "lickety" sound could have been inspired by the quick, repetitive motion of a tongue.
* Descriptive Phrase: It could have evolved from a simple, descriptive phrase used to describe something moving very quickly.
While the exact origin remains a bit of a mystery, the phrase's evocative nature makes it a memorable and effective way to express rapid speed.
