What is the Greek word for cannot be cut?

There isn't one single perfect Greek word for "cannot be cut" that covers all contexts. The best translation depends on *what* can't be cut and *why*. Here are some options with slightly different nuances:

* ἀτέμνιστος (atémnistos): This is probably the closest single word. It literally means "uncuttable," implying an inherent resistance to being cut.

* You could also use a phrase like οὐκ ἀποτέμνεται (ouk apotémnetai): This translates to "it is not cut off" or "it cannot be cut off," and is more suitable for things that resist being severed.

* For something that's indivisible in a more abstract sense (like a concept), you might use a phrase incorporating words like ἀδιαίρετος (adiairetós) - indivisible, or ἄτμητος (áthētos) - uncut, though the latter is more literal than implying uncuttability.

Therefore, ἀτέμνιστος (atémnistos) is likely the best single-word approximation, but a more descriptive phrase might be necessary for accuracy depending on the specific context.
