Distinctions: Action-Manner, Ground, Action-Result (Hover over a relationship to see how it differs.)
Action-Manner (Ac/Mn) vs Action-Purpose (Ac/Pur)
Action-Manner is support by restatement, whereas Action-Result and Action-Purpose are support by distinct statement. Therefore the manner is not telling you something entirely distinct from the action, but telling you more information about the action.
Bill threw the ball by swinging his arm around in a circle. (Action-Manner)
Bill threw the ball in order to knock over the cans. (Action-Purpose)
Ground (G) vs Action-Purpose (Ac/Pur)
Both Ground and Action-Purpose answer the question "Why?". The difference is that with Ground, the supported action or reality looks back (chronologically or logically) to the truth of the grounding idea. Conversely, with Action-Purpose, the action looks forward with the intention to bring about the purposed result.
Bill kicked the football because he was the field goal kicker. (Ground)
Bill kicked the football in order to attempt a field goal. (Action-Purpose)
Action-Result (Ac/Res) vs Action-Purpose (Ac/Pur)
The difference between Action-Result and Action-Purpose lies in the question of intention. Was it a purpose intended by the actor? Or was it a result, not particularly sought by the one doing the action? (Note: Actions with non-personal actors will be Action-Result.)
The line between these two can be thin, however, when God is the actor. (Could we not say that God has purpose in every action?) In this case, ask the question of whether purpose is being emphasized.
Bill threw the ball and it broke his grandmother's vase. (Action-Result)
Bill threw the ball in order to knock over the cans. (Action-Purpose)
