PREFIXES GRADE 6TH Prefixes-small but meaningful letter groups added before a base word or rootchange the meaning of a word. Knowing the meaning of these prefixes, together with the meaning of common base words and Greek and Latin roots, will give students the tools for unlocking the meanings of hundreds of words. ln addition to teaching these prefixes directly, it is also a good idea to explain prefixes and their meanings when students encounter them in new vocabulary words throughout the year.

Suffixes usually signify the part of speech and usually add meaning. ln this list, suffixes are grouped by part of speech. Some suffixes are best understood, not as having a particular meaning but as expressing grammar or syntax. These suffixes enable you to express an idea in many different ways by using the variation of the key word that best fits the sentence structure. For example, in the sentences: The boy is quiet. The boy played quietly. The boy's quiefness was undisturbed. The word quiet was altered to fit the sentence structure. ln (1) it is used as an adjective; in (2) the suffix -/y was added so that it could be used as an adverb; in (3) the suffixness was added so that it could be used as a noun.

The study of word origins, or etymology, is a fascinating subject. The Greek and Latin roots in this list can form the basis for a vocabulary-building course. Roots are taught successfully in families such as microscope, telescope, periscope, to illustrate that scope means "see." ln the following list, Greek roots are indicated with "g" and Latin roots with "1."
