Not intending to make light of what is, clearly, a horrid affliction which many posters have to deal with: but the word "vertigo" has been ruined for me permanently, by reason of my first encounter with it, in childhood. My parents were fans of Ogden Nash, and we had in the house several books of his verse. I came to love much of Ogden's stuff -- especially his antics as, likely, the ultimate perpetrator on the English language, of pun-type atrocities. I first came upon the word -- and needed to enquire as to its meaning -- in a poem of his about suicide; which ends with his telling of a businessman in dire financial straits, who ended it all by jumping from the top of a skyscraper --
"And one of his partners asked, has he vertigo? And the other glanced out and down and said, Oh, no, only about ten feet more."
