Latin Roots, Prefixes, and SuffixesLatin was the language spoken by the ancient Romans. As the Romans conquered most of Europe, the Latin language spread throughout the region. Over time, the Latin spoken in different areas developed into separate languages, including Italian, French, Spanish, and Portuguese. These languages are considered “sisters,” as they all descended from Latin, their “mother” language.
In 1066 England was conquered by William, duke of Normandy, which is in northern France. For several hundred years after the Norman invasion, French was the language of court and polite society in England. It was during this period that many French words were borrowed into English. Linguists estimate that some 60% of our common everyday vocabulary today comes from French. Thus many Latin words came into English indirectly through French. Many Latin words came into English directly, though, too. Monks from Rome brought religious vocabulary as well as Christianity to England beginning in the 6th century. From the Middle Ages onward many scientific, scholarly, and legal terms were borrowed from Latin. During the 17th and 18th centuries, dictionary writers and grammarians generally felt that English was an imperfect language whereas Latin was perfect. In order to improve the language, they deliberately made up a lot of English words from Latin words. For example, fraternity, from Latin fraternitas, was thought to be better than the native English word brotherhood. Many English words and word parts can be traced back to Latin and Greek. The following table lists some common Latin roots. Latin root | Basic meaning | Example words |
---|
-dict- | to say | contradict, dictate, diction, edict, predict | -duc- | to lead, bring, take | deduce, produce, reduce | -gress- | to walk | digress, progress, transgress | -ject- | to throw | eject, inject, interject, project, reject, subject | -pel- | to drive | compel, dispel, impel, repel | -pend- | to hang | append, depend, impend, pendant, pendulum | -port- | to carry | comport, deport, export, import, report, support | -scrib-, -script- | to write | describe, description, prescribe, prescription, subscribe, subscription, transcribe, transcription | -tract- | to pull, drag, draw | attract, contract, detract, extract, protract, retract, traction | -vert- | to turn | convert, divert, invert, revert |
From the example words in the above table, it is easy to see how roots combine with prefixes to form new words. For example, the root -tract-, meaning “to pull,” can combine with a number of prefixes, including de- and re-. Detract means literally “to pull away” (de-, “away, off”) and retract means literally “to pull back” (re-, “again, back”). The following table gives a list of Latin prefixes and their basic meanings. Latin prefix | Basic meaning | Example words |
---|
co- | together | coauthor, coedit, coheir | de- | away, off; generally indicates reversal or removal in English | deactivate, debone, defrost, decompress, deplane | dis- | not, not any | disbelief, discomfort, discredit, disrepair, disrespect | inter- | between, among | international, interfaith, intertwine, intercellular, interject | non- | not | nonessential, nonmetallic, nonresident, nonviolence, nonskid, nonstop | post- | after | postdate, postwar, postnasal, postnatal | pre- | before | preconceive, preexist, premeditate, predispose, prepossess, prepay | re- | again; back, backward | rearrange, rebuild, recall, remake, rerun, rewrite | sub- | under | submarine, subsoil, subway, subhuman, substandard | trans- | across, beyond, through | transatlantic, transpolar |
Words and word roots may also combine with suffixes. Here are examples of some important English suffixes that come from Latin: Latin suffix | Basic meaning | Example words |
---|
-able, -ible | forms adjectives and means “capable or worthy of” | likable, flexible | -ation | forms nouns from verbs | creation, civilization, automation, speculation, information | -fy, -ify | forms verbs and means “to make or cause to become” | purify, acidify, humidify | -ment | forms nouns from verbs | entertainment, amazement, statement, banishment | -ty, -ity | forms nouns from adjectives | subtlety, certainty, cruelty, frailty, loyalty, royalty; eccentricity, electricity, peculiarity, similarity, technicality |
Zool 250 - Latin & Greek Roots Index HOW TO USE THE INDEX: Many technical terms, names of biological structures, and names of taxa, are formed from Greek and Latin roots. If you are familiar with these roots, you can 'translate' the technical terms into English. One particularly useful example is the names of taxa. The formal taxonomic names for many animal groups (from phylum down to species) are often formed from roots that refer to distinctive features of the animals. When used in pairs, such as in the familiar Latin binomials for genus and species, both the genus and species names are often descriptive. | EXAMPLES: - Echinodermata, a phylum name that means 'spiny-' (echino-) 'skin' (derm), or the 'spiny skinned' animals
- Arthropoda, a phylum name that means 'joint-' (arthro-) 'foot' (pod), or the 'jointed-foot' animals
- Archaeopteyx, a genus name that means 'ancient-' (archae-) 'wing' (pter), or the 'ancient-winged' animals
- Amphioxus, a common name that means 'double-' (amphi-) 'pointed' (oxus), or the 'double-pointed' animals (originally it was a genus name for the lancelets, which are pointed on both ends)
- Homo erectus a genus & species combination that means 'man' (homo) 'upright' (erectus), or 'upright man'
