A review of Basics of Verbal Aspect in Biblical Greek, by Constantine Campbell:

The idea of “aspect” in NT Greek studies has risen to a position of attention and controversy recently. While there are still many details that need to be researched and clarified further, verbal aspect provides a more precise insight into the Greek verb system by better explaining the associations between verb forms and their contextual meanings.

Constantine Campbell’s book Basics of Verbal Aspect in Biblical Greek is the first reading I’ve done on this subject. I found it to be a clear and manageable introduction to a detailed topic. Through clear writing, effective illustrations and review, Campbell opens the formerly-locked box of verbal aspect for Greek students.

After demonstrating the need for understanding aspect (ch. 1), the author briefly chronicles the history of aspect study (ch. 2). Chapters 3-5 present perfective and imperfective aspects and explain their impact on our understanding of the tense-forms. Chapters 6-10 then elaborate on the specifics of aspect with reference to each tense. Helpful exercises are included for the reader to test his understanding.

A sample chapter is available here, and the book is available from Zondervan here.
