     In a typical lexicalist approach (e.g. Koontz-Garboden 2006), the unmarked lexeme is taken as lexically listed, even if its meaning (as it often does) includes templatic entailments, and the derivational morphology is taken to operate on the underived form to yield the derived form. This is the case not only morphologically, but also semantically.
