English is a morpho-phonemic language; therefore, students need both phonics knowledge and knowledge of morphology in order to fully understand the written code of English.
Morphemes are units of meaning within words - these are often referred to as prefixes, suffixes, and roots. Many of the morphemes taught within the Logic of English curriculum are Latin and Greek roots. Having knowledge of morphemes can help students determine the meaning of unknown vocabulary words.
For example, knowing the morpheme BENE means "good" would help a student know that a benefactor is someone who does something good. Studying morphemes will help students begin to connect words based on meaning which will help them orthographically map words within the brain for better understanding and retention.
Studying morphemes can help students in cross-curricular word study. Morphemes will help students, especially in science, to identify the meaning of new vocabulary.
