The story of the word

The science acquired its name in French in the 1890s, as spéléologie, at the moment when Édouard-Alfred Martel was lowering himself down French sinkholes on rope ladders and turning cave exploration into a discipline with instruments and reports. English took the word almost immediately. Spelunker comes from Latin spelunca, itself borrowed from Greek σπῆλυγξ, so the scientist and the weekend caver carry cousin words that travelled by different roads.
