Many root words in science are based on Greek and Latin terms. In fact, the “CH” sound is always
pronounced as a “K” because of the pronunciation of the Greek root words. (e.g. chemistry, technology,
archaeology, chromosome, chitin….)
Below are some prefixes (word beginnings) and that give added meaning to the root words.
