What does inexecutable mean?
Inexecutable is an adjective meaning incapable of being carried out or put into effect. It applies most naturally to a plan, agreement, instruction, or piece of code that cannot be performed, implemented, or made operational. The word is much rarer than its negation, executable, and typically appears in formal, technical, or legal prose. In a modern computing context, it distinguishes something fundamentally unable to run from something that is merely unfinished, faulty, or awaiting permission. A specification may be perfectly intelligible yet inexecutable because it depends on an unavailable capability. The term can also carry an implication of impracticability rather than literal impossibility: an order may be legally valid but inexecutable in the current circumstances. Outside specialist writing, plainer phrases such as impossible to carry out or not implementable are usually clearer and more idiomatic.

Where does inexecutable come from?
Inexecutable was formed in English with the prefix in- and the adjective executable, reversing the meaning of executability. Executable derives from Latin exsecutus, the past participle of exsequi, meaning to follow out or pursue, which also underlies execute and cognates such as executive and sequel. The prefixation follows the ordinary English pattern for forming an adjective meaning unable to undergo a specified action.
How inexecutable is actually used
This is a rare word found chiefly in formal, legal, technical, and literary writing. It may imply practical impossibility rather than absolute logical impossibility, and ordinary prose will often be clearer with a phrase such as impossible to carry out or not implementable.
