Etymology

Origin of specificity

First recorded in 1875–80; specific + -ity

Explanation

Specificity is the goal of anyone who wants to know — or give — every single detail. If your friend's story is too vague, ask for specificity when things aren't clear. Specificity may look hard to pronounce, but if you remember that the first syllable rhymes with guess, the rest will flow easily: "spes-uh-FIS-uh-tee." Now try specificus, the Latin word at the root of specificity and the word species. Those words may not seem related — until you think about the classification of living things: kingdom, phylum, class, order, family, genus, species. Species is the most specific in the hierarchy!
