Fred Jehle, formerly a professor at Indiana University-Purdue University Fort Wayne, published approximately 600 verbs, fully conjugated in all moods and tenses, on his website in 1998. The resource helped students improve their verb use in addition to a variety of notes on other aspects of the language.
The roughly 600 verbs converted to 11,467 combinations of moods + tenses.
