The Difference Between « depuis », « pendant » and « il y a » ⏳

📝 Why is it confusing?

All three talk about time, but they are used in different contexts:

• depuis → action started in the past and still continues

• pendant → duration of an action (past, present or future)

• il y a → ago (when something happened in the past)

---

📌 1. Depuis = since / for (still ongoing)

👉 Used with the present tense (or imperfect) to indicate that something began in the past and continues now.

• Elle travaille ici depuis trois ans.
  = She has been working here for three years.

• Nous attendons depuis une heure. ⏰
  = We have been waiting for an hour.
