Peculiar Has Latin Roots

It might strike you as odd that the origins of peculiar are livestock-related, so let us explain. The word's Latin ancestor, peculiaris, means "privately owned, extraordinary"; it traces back to pecu, meaning "cattle," by way of peculium, meaning "private property"—cattle of course being a particular kind of private property. Given the monetary value historically placed in cattle, it makes sense that pecu has given us several money-related words, including pecuniary ("of or relating to money"), peculate ("to embezzle"), and impecunious ("having very little or no money"). Peculiar honed in on the "extraordinary" meaning of peculiaris, applying to what is characteristic of only one individual, group, or thing. In modern use that sense is commonly followed by the preposition to, as in "a tradition peculiar to their family." The "odd" and "eccentric" meanings of peculiar are extensions of that sense, and are now the word's most common applications.
