Consistency: Avoiding Shifts in Person, Number, Tense, Voice, and Mood

A draft creates a contract with its reader. If it begins in past tense and third person, the reader expects that frame to continue until the meaning gives a reason to change. Editing questions often hide one unnecessary shift inside an otherwise smooth paragraph.

How do you know whether a shift is wrong?

First identify the pattern established by nearby sentences. Residents bring their bins to the curb, and you should remove the lids shifts from third person to second person for no reason. Repair it as Residents bring their bins to the curb, and they should remove the lids. A shift is correct when time or purpose truly changes: Last year the clinic closed at five; now it stays open until eight.

Which shifts are easiest to miss?

Person and number shifts can hide behind pronouns. Tense shifts often appear in a single verb. Voice shifts become awkward when a sentence changes focus halfway through. Mood shifts occur when a list starts with commands and ends with a statement: Check the address, seal the envelope, and the stamp should be added. Keep the commands parallel: Check, seal, and add.

Technical Communication teaches the exact skill this lesson develops. Watch for the decision you can reuse when you return to a full draft.

A four-step test-day routine

1. Mark the paragraph’s established pattern.
2. Circle the word where the pattern changes.
3. Ask whether meaning requires that change.
4. If not, revise the outlier and reread the whole passage.

Practice

1. Repair: “A driver should check the mirrors before you start the car.”
2. Is the shift correct? “Yesterday we tested the alarm; today we replace it.”
3. Repair the command list: “Open the file, read the note, and the form should be signed.”
4. What nearby evidence helps you fix a tense shift?
5. When is a voice shift acceptable?
6. Why should you reread beyond the edited sentence?

Answers and reasons

1. A driver should check the mirrors before starting the car.
2. Yes. The time words justify the tense change.
3. Open the file, read the note, and sign the form.
4. The established verbs and time markers in surrounding sentences.
5. When the writer intentionally changes focus and the new focus improves meaning.
6. Consistency is a passage-level relationship, so the surrounding pattern proves the repair.
