Figure 1 shows the structure of a simple inheritancebased lexicon with some abstract high-level structure (CATEGORY, VERB, NOUN), then a layer of lexemes (WALK, TALK, HOUSE, BANK), and below that a layer of word forms (walks, walking, talked, house, houses, banks, as well as many more).
the word form walks inherits information from the lexeme WALK, which inherits from abstract node VERB and then abstract node CATEGORY.
