Greek Infinitive

An infinitive is a verbal noun and is not declined. It has no time significance (because it is not an indicative) and has the aspects: continous, underfined or perfected. These can be translated as "to continually run" (continous), "to run" (underfined) and "to have ran" (perfected).
