Word Roots and Vocabulary Building

Use prefixes, roots, and suffixes to decode unfamiliar vocabulary you encounter in standardized test reading passages.

What You'll Learn

Identify prefixes, roots, and suffixes as the building blocks of unfamiliar test vocabulary

Apply a step-by-step strategy: isolate the root, interpret each affix, then verify against context

Recognize high-frequency Greek and Latin roots that recur across science, social studies, and literary passages

Compare candidate meanings against surrounding context clues to confirm the best inference

Distinguish the literal meaning built from morphology from the shaded meaning supplied by tone and context

Practice decoding multisyllabic words under timed conditions similar to actual exam settings

What You'll Practice

Decompose multisyllabic passage vocabulary into prefix, root, and suffix components

Match unfamiliar words to plausible meanings using morphology plus surrounding context clues

Build a personal reference list of roots and affixes drawn from previously missed test vocabulary

Time yourself decoding five unfamiliar words pulled from a practice reading passage

Why This Matters

Standardized test passages routinely include vocabulary you have never encountered, and you cannot pause to check a dictionary. Recognizing a familiar root or affix lets you infer a plausible meaning within seconds, keeping your reading pace steady and protecting your comprehension score under timed conditions.
