““The Greek terms whose meanings the term "progressive" is meant to cover are 'ateles' and 'paratatikos'. 'Ateles' is formed from alpha-privative and 'telos', meaning "end" or "fulfillment". In light of 'ateles' we might have termed this aspect the "unfulfilled" or "incomplete" aspect. 'Paratatikos' is derived from the preposition 'para' ("alongside") and the verb 'teino' ("to stretch") and denotes an action as continuing or extending.””
