Agreement in person (point-of-view)
Be consistent with the point-of-view that you use in your writing and the pronouns you use to indicate your point-of-view.
There are three possible points-of-view:
- First person: "I", "me", "my"
- Second person: "You", "yours"
- Third person: "he", "she", "they", "it", etc.
Don't switch your point-of-view mid-sentence. For example, "If a student hands in a late assignment, you will have marks deducted" (mixes the third-person "student" with the first-person "you"). The correct version is either, "If a student hands in a late assignment, the teacher will deduct marks from their grade", or "If you hand in a late assignment, the teacher will deduct marks from your grade".
