"Forever and ever" is the root word that signifies the meaning of "in-" in endless.
<h3>What does the word interminable mean?</h3>
Interminable is defined as something that is limitless or appears to continue on indefinitely.
In the lines "interminable serpents of smoke trailed themselves for ever and ever, and never got uncoiled."
Webster's Dictionary defines interminable as "endless; never-ending." The smoke serpents were like that—they never stopped moving. As a result, the prefix "in-" denotes the chimney's never-ending smoke.
