🔴 1. BEFORE = Earlier than a time
👉 Use before when something happens earlier than a specific time or event.
🧠 Simple idea:
👉 BEFORE = earlier
✅ Examples:
- I finished my homework before dinner
- She arrived before 7 PM
🔵 2. DURING = In the middle of a period
👉 Use during when something happens inside a period of time (not at the start or end).
🧠 Simple idea:
👉 DURING = in the middle
✅ Examples:
- He slept during the movie
- We talked during the class
🟢 3. SINCE = From past until now
👉 Use since when an action started in the past and is still continuing now.
🧠 Simple idea:
👉 SINCE = from a starting point (past → now)
✅ Examples:
- I have lived here since 2010
- She has been studying since morning
🟡 4. FOR = Duration (how long)
👉 Use for to show how long something happens.
🧠 Simple idea:
👉 FOR = length of time
✅ Examples:
- I studied for 2 hours
- She lived there for 5 years
⚠️ IMPORTANT: SINCE vs FOR (Very Clear)
This is where students get confused 👇
🔹 SINCE = Starting point
- since 2010
- since morning
🔹 FOR = Duration
- for 2 years
- for 3 hours
🧠 Easy Trick
👉 Since = point (start)
👉 For = period (length)
✅ Compare:
- I have lived here since 2010 (start time)
- I have lived here for 10 years (duration)
🎯 Final Summary (Easy to Remember)
👉 Before = earlier
👉 During = in the middle
👉 Since = from past until now
👉 For = how long
