Notes on Meaning
The core meaning of "inextensible" is the inability to be lengthened. While its primary use is physical (e.g., materials), it can be applied metaphorically to abstract concepts like timeframes or rules, indicating they cannot be extended or expanded. The reference to "not extensile" often pertains to biological parts, like claws or tongues, that cannot be protruded.
