概要	-Ed is arguably the most multifunctional suffix in Present-day English. In verbal inflection, it produces the past tense, perfective, and passive forms of a verb, and the latter two forms are syncretic with adjectival participles. While this range of formal identity is puzzling enough, -ed is also observed in denominal adjectivalization. In this paper, we provide further evidence of the multifunctionality of -ed in the denominal domain and offer a lexicalist analysis of it without reference to the concept of morphome, i.e. purely morphological mapping function (Aronoff 1994). A close look at a small pocket of the English lexicon will reveal a more satisfactory approach to the messy landscape involving -ed.
