1. Roots and Affixes
Students will determine the meaning of vocabulary using linguistic roots and affixes (e.g. Greek, Anglo-Saxon, Latin). Students will utilize these skills throughout the year.

2. ROOT, AFFIX, PREFIX, and SUFFIX
An English word can consist of three parts: the root, a prefix and a suffix. The root is the part of the word that contains the basic meaning (definition) of the word. The root is the base element of the word. A prefix is a word element that is placed in front of a root. A prefix changes the word's meaning or makes a new word. A suffix is a word element that is placed after the root. Prefixes and suffixes are called affixes because they are attached to a root.

3. Roots and Affixes A root is the part of a word that contains the
basic word (definition) of the word.
A prefix is a letter or a group of letters attached to the beginning of a word that partly indicates its meaning. For example, the word prefix itself begins with a prefix--pre-, which generally means "before."

4. Roots and Affixes PREFIX — a word part that can be added to the
beginning of a word to make a new word.
SUFFIX — a word part that can be added to the end
of a word to make a new word.
ROOT —the word that’s left over when
prefixes and suffixes have been removed.

MAKE SURE you return to the passage to use the context to assist you in determining the meaning of the unknown word. WATCH OUT! for definitions that aren’t supported by context
