To authorize or give authority to; an archaic or rare form meaning to empower or grant official permission.
From Latin 'auctoritas' (authority) combined with the verb-forming suffix '-ate', creating a back-formation or rare variant of 'authorize'.
The '-ate' suffix is English's favorite way to turn nouns into verbs (like 'author' becomes 'author' used as a verb, or 'active' becomes 'activate')—'auctorizate' is just a fancy version that never really caught on!
