No reasonable person can look at the word Venus without trying to rhyme it with something. It's like wombat: it's impossible. This is a mite unfair on the poor old lady. Venus has got a terrible press. From her do we get venal, venom, venial and venereal disease.
Vener is the Latin genitive. One early science fiction writer, W.A. Lach-Szyrma (of whom much much more later), wrote:
I must also apologise for the word "Venusian". I know well that compounds ought to be derived from the genitive Veneris; but these are already connected with ideas opposed to those I wish to convey.
Having a planet named after you is small compensation for such indignity. Even Shakespeare in Venus and Adonis makes her out as a slightly dotty and unwanted nymphomaniac.
Her Greek equivalent Aphrodite rhymes with nightie and gave us aphrodisiac.
I have already blogged about Venus of the Beautiful Bottom, and know nothing about fly-traps.
