Both “yet” and “already” are adverbs used mainly with the present perfect tense:

They both talk about time, but they express different meanings.

Meaning:

👉 Example idea:

❓ What “yet” means

⚖️ Key difference (simple comparison)
| Word | Meaning | Sentence type | Idea |
|---|---|---|---|
| already | finished | positive | sooner than expected |
| yet | not finished | negative / question | expected but not done |
🔁 Compare the same situation
Let’s use the same example to see the difference clearly:
Situation: homework
- I have already finished my homework.
👉 It is done. - I haven’t finished my homework yet.
👉 It is not done, but I will finish it.
📍 Position in a sentence
“Already”
Usually goes:
- before the main verb
Examples:
- I have already eaten.
- She has already left.
“Yet”
Usually goes:
- at the end of the sentence
Examples:
- I haven’t eaten yet.
- Has she left yet?
💬 Use in conversation

⚠️ Common mistakes
❌ Incorrect:
- I already haven’t finished.
✅ Correct:
- I haven’t finished yet.
❌ Incorrect:
- Have you already finished yet?
✅ Correct:
- Have you finished yet?
- Have you already finished? (different meaning)
👉 Difference:
- “Have you finished yet?” → just asking

🧠 Easy way to remember
👉 Think like this:
- already = ✔ done
- yet = ⏳ not done
🎯 Teaching tip (for elementary ESL)
Use a timeline:
- Past → Now
- “already” = action is completed before now
- “yet” = action has not reached now
You can also act it out:
- Finish a task → “I’ve already finished!”
- Still working → “I haven’t finished yet!”
👍 Final summary
- “Already” is used in positive sentences to show something is finished, often earlier than expected.
- “Yet” is used in negative sentences and questions to show something has not happened, but is expected to happen.
