SVUSD – Grade 4 Lesson 30 Latin Roots: graph/gram Generalization: Root words are parts of Latin and Greek words. In English they do not stand on their own as independent words; they are always preceded or followed (or both) by affixes. Spelling, syllabication, and derivational generalizations are used when adding prefixes and suffixes to roots. graph = writing gram = drawn, written Note: Base words are elements that can be used to build words by adding affixes but are also complete words in themselves (power, powerful, powerless). graph gram graph graphic graphite autograph photograph photographer paragraph telegraph polygraph phonograph pictograph biography calligraphy geography oceanography typography stenographer seismographer bibliography cinematography choreography telegram monogram cardiogram cablegram centigram milligram kilogram hologram
