To remove or separate donkey-like qualities; a very rare term with uncertain modern usage.
From dis- + asinate (from Latin asinus, meaning donkey). This is an extremely obscure word that appears in some historical dictionaries but is practically never used in modern English.
This word is so rare that even most dictionaries don't include it—it's a perfect example of how many words were theoretically possible in English even if they were never actually used by speakers.
