What is hanky dory?

Answer 1

I think you mean 'hunky-dory'

The Random House Historical Dictionary of American Slangsuggests that the term may have been introduced in America about 1865 by a popular variety performer named Japanese Tommy. Other references suggest that it may have been sailors' slang for a street in Yokohama that catered for what one might describe as the special needs of sailors. In Yokohama today a broad thoroughfare called Honcho-dori runs from the centre of the city to the port area, so one that would have been familiar to sailors (dori is the Japanese word for a road, in particular a broad or important one).

What seems certain is that hunky-dory was a play on an existing sense of the word hunky for something that was fine, splendid or satisfactory. In turn, this probably derives from the adjective hunk, which means that one is all right or in a safe or good position. This derives from the Dutch honk, meaning "goal" or "home" in a Frisian variant of the game of tag. This word (and presumably the game, too) was said to have been taken by the Dutch to New Amsterdam, later New York, but was first recorded only around the 1840s. It has links to another reduplicated term, hunkum-bunkum. Though the first part sounds a bit like the hunker of hunker down (which is also of Dutch origin), the words seem not to be related.

It may be that hunky-dory was the result of a bilingual pun, perhaps invented because American sailors knew the word dori and prefixed it with hunky as an imagined Japanese street of earthly delights.
