Hunky-dory

AOK

This phrase originated from military radio code and means everything is perfectly fine, often used in casual conversation.

"Hunky-dory" is an old-fashioned slang phrase meaning everything is fine or in perfect order, just like "AOK." The clue plays on synonyms—both expressions signal that things are going well or are satisfactory. "AOK" (or "A-OK") became popular in the mid-20th century, especially in NASA communications, reinforcing its meaning of flawless or fully approved. So, the answer is simply another way to say the same thing.
