Certain sets of words in the English language tend to confuse writers. I have found the following to be among them:
SET / SAT
Despite the best efforts of our elementary school teachers, we writers (and others) still get these two words confused. The big difference here is that set (present, past, and past participle form of the verb to set: set, set, set) takes an object while sat (past and past participle form of the verb to sit: sit, sat, sat) does not. In other words, it is proper to say that you set something down but it is not proper to say that you sat it down.
The big confusion here seems to come when a person is the object, but in grammar even a non-object can be the object of a verb (or preposition). Meanwhile, the opposite is true for set. This verb must have an object and therefore cannot sit alone.
