Here are some possible interpretations, considering common misspellings and potential regional variations:
* "Lither" is an archaic word for "lazy" or "sluggish." So, "lithering" could be a misspelling of "lither," meaning someone who is lazy or sluggish.
* "Slithering": This is a common misspelling of "slithering," which means moving smoothly and silently, like a snake.
* "Littering": This is another possibility, meaning to scatter trash or debris carelessly.
To understand the intended meaning, it's important to consider the context in which you encountered the word "lithering."
For example, if you saw "lithering" in a sentence like "The snake was lithering through the grass," it's likely a misspelling of "slithering."
If you can provide more context, I can help you determine the intended meaning more accurately.
