LMBM is a lexeme-based morphologyMorphology
Robert Beard is professor emeritus at Bucknell University

LMBMLexeme-Morpheme Base Morphology (LMBM) is known for its rigorous distinction of lexemes and grammatical morphemes. The theory is formally described in Lexeme - Morpheme Base Morphology, Albany, NY: SUNY Press, 1995. This site explains one of the four basic hypotheses of LMBM: The Separation Hypothesis. For the other three, the Aristotelean Hypothesis, Unitary Grammatical Functions, and the Base Rule Theory, refer to the book. In this document you may click 'Outline of the Theory' below to begin a short overview of the Separation Hypothesis, or click any of the subsections to move directly to a specific topic, including general topics outside LMBM but related to the study of morphology. The appropriate address for comments and questions is located at the bottom of this page.
