Q: Think of a word containing the consecutive letters O-K. Remove the O-K, and you'll get a new word that's a synonym of the first word. What words are these?The first thought I had when I figured out this puzzle was the Latin phrase "cavit lukom". You can argue that I haven't got the right conjugation but looking back on it, I still contend that the clue is useful nonetheless.
Edit: If you followed my hints you would take that bogus Latin phrase and write it backwards as MOKULTIVAC. After removing the OK you have MULTIVAC. If you Google for that you'll find that Isaac Asimov had a loosely connected series of stories involving a fictional computer called Multivac. One of those stories was Jokester (1956).
A: JOKESTER --> JESTER
