The Four Faces of a Verb
5.1 🗺️ The Four Faces of a Verb
Welcome to Module 5! To build any tense in English, you must first know how a verb changes its physical form. Every English verb has four principal forms (we call them the “Four Faces”).
📊 The Principal Forms Matrix
| Form Name | What it represents | Example (Regular) | Example (Irregular) |
|---|---|---|---|
| 1. Base Form | The raw dictionary word; used for present habits and facts. | work | go |
| 2. Past Simple | A completed action at a specific point in past time. | worked | went |
| 3. Past Participle | Used after helpers (have/had) or in passive sentences. | worked | gone |
| 4. Present Participle | Used after be helpers (am/is/are) to show ongoing action. | working | going |
📝 Real-World Examples Explained
1. The Regular Face Shift
- Base: “I work here every day.” (Present habit)
- Past Simple: “I worked late yesterday.” (Completed past)
- Past Participle: “I have worked here for a year.” (Present perfect timeline)
- Present Participle: “I am working on a report right now.” (Ongoing action)
2. The Irregular Face Shift
- Base: “They go to Japan every winter.” (Present routine)
- Past Simple: “They went to Tokyo last week.” (Completed past point)
- Past Participle: “They have gone to the library.” (Action finished up to now)
- Present Participle: “They are going to the meeting room now.” (Live movement)
🚫 Common Mistakes: Correct vs. Incorrect
1. Using the Past Simple Face After “Have”
❌ Incorrect: “The management team has went to the conference room.”
✅ Correct: “The management team has gone to the conference room.”
Why it’s wrong: After the present perfect helper has or have, you must use the third face (Past Participle: gone), never the second face (went).
