A motive is a reason why someone does or says something.
Sometimes a person’s motive is obvious: the reason why my sister bought me a present was because it was my birthday.
But very often, we have to guess a person’s motives based on what we know of the person and the situation.
Did you think of these?
Without any context we can’t really know but in literature, and in real life, when we know something about a person and want is happening, we can make a fairly good guess about motives.
