Cause and reason are often confused in meaning. Reason is what one produces to account for or justify an effect; cause is what actually produces an effect."His reason for speaking is clear." "The cause of his leaving early is debatable." Cause of and on account of do not have the same meaning."The cause of my lateness was a slow bus" is preferable to "The cause of my lateness was on account of my bus was slow." See also because.
