List of Latin and Greek Words Commonly Used in Systematic Names

This list of Latin and Greek words commonly used in systematic names is intended to help those unfamiliar with classical languages to understand and remember the scientific names of organisms. The binomial nomenclature used for animals and plants is largely derived from Latin and Greek words, as are some of the names used for higher taxa, such as orders and above. At the time when biologist Carolus Linnaeus (1707–1778) published the books which are now accepted as the starting point of binomial nomenclature, Latin was used in Western Europe as the common language of science, and scientific names were in Latin or Greek: Linnaeus continued this practice.

Although Latin is now largely unused except by classical scholars, or for certain purposes in botany, medicine and the Roman Catholic Church, Latin can still be found in scientific names. It is helpful to be able to understand the source of scientific names. While the Latin names do not always correspond to the current English common names, they are often related, and if their meanings are understood, they are easier to recall. The binomial name often reflects limited knowledge or hearsay about a species at the time it was named. For instance Pan troglodytes, the chimpanzee, and Troglodytes troglodytes, the wren, are not necessarily cave-dwellers.

Often a genus name or specific descriptor is simply the Latin or Greek name for the animal (e.g. Canis is Latin for a dog). These words are not included in the table below, because they will only occur for one or two taxa. Instead, the words listed below are the common adjectives and other modifiers that repeatedly occur in the scientific names of many organisms (in more than one genus).

Only root words are listed, while variants are omitted. So, verus is listed without the variants for Aloe vera or Galium verum. Words that are very similar to their English forms have also been omitted.
