How are words related?
I argue in favour of the notions ‘word (form)’, ‘lexeme’, ‘paradigm’ against Distributed Morphology claims that lexical roots are indexed only by their form. That approach entails there can be no suppletion in lexical items. In addition to the obvious counterexamples I point out more subtle cases such as Russian prefixed verbs. Following Spencer (2013) I propose that a lexical entry is identified with a unique lexemic index. Transpositions, such as participles, preserve their base verb’s lexemic index (cf inflected forms). They contrast with transpositional lexemes such as prepositional or participle-form adjectives such as interesting. They share their semantic content with their base verb yet they are distinct lexemes, hence, are furnished with a distinct lexemic index.
