Question

Quizplus · Accepted Answer

Olivia's difficulty with using plurals and past tense endings suggest a problem with morphology, which is the study of word formation and structure. Morphology includes the rules for adding plural /s/ or past-tense /ed/ to words. This is different from phonology (the study of speech sounds), grammar (the study of sentence structure), or semantics (the study of word meanings).
